DS70005349C-page 21 dsPIC33CK256MP508 FAMILY NOTES: DS70005349C-page 22 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 2.0 2.1 GUIDELINES FOR GETTING STARTED WITH 16-BIT DIGITAL SIGNAL CONTROLLERS Basic Connection Requirements Getting started with the family devices of the dsPIC33CK256MP508 requires attention to a minimal set of device pin connections before proceeding with development. The following is a list of pin names which must always be connected: * All VDD and VSS pins (see Section 2.2 "Decoupling Capacitors") * All AVDD and AVSS pins regardless if ADC module is not used (see Section 2.2 "Decoupling Capacitors") * MCLR pin (see Section 2.3 "Master Clear (MCLR) Pin") * PGCx/PGDx pins used for In-Circuit Serial ProgrammingTM (ICSPTM) and debugging purposes (see Section 2.4 "ICSP Pins") * OSCI and OSCO pins when an external oscillator source is used (see Section 2.5 "External Oscillator Pins") 2017-2018 Microchip Technology Inc. 2.2 Decoupling Capacitors The use of decoupling capacitors on every pair of power supply pins, such as VDD, VSS, AVDD and AVSS is required. Consider the following criteria when using decoupling capacitors: * Value and type of capacitor: Recommendation of 0.1 F (100 nF), 10-20V. This capacitor should be a low-ESR and have resonance frequency in the range of 20 MHz and higher. It is recommended to use ceramic capacitors. * Placement on the printed circuit board: The decoupling capacitors should be placed as close to the pins as possible. It is recommended to place the capacitors on the same side of the board as the device. If space is constricted, the capacitor can be placed on another layer on the PCB using a via; however, ensure that the trace length from the pin to the capacitor is within one-quarter inch (6 mm) in length. * Handling high-frequency noise: If the board is experiencing high-frequency noise, above tens of MHz, add a second ceramic-type capacitor in parallel to the above described decoupling capacitor. The value of the second capacitor can be in the range of 0.01 F to 0.001 F. Place this second capacitor next to the primary decoupling capacitor. In high-speed circuit designs, consider implementing a decade pair of capacitances as close to the power and ground pins as possible. For example, 0.1 F in parallel with 0.001 F. * Maximizing performance: On the board layout from the power supply circuit, run the power and return traces to the decoupling capacitors first, and then to the device pins. This ensures that the decoupling capacitors are first in the power chain. Equally important is to keep the trace length between the capacitor and the power pins to a minimum, thereby reducing PCB track inductance. DS70005349C-page 23 dsPIC33CK256MP508 FAMILY FIGURE 2-1: RECOMMENDED MINIMUM CONNECTION 0.1 F Ceramic R R1 VSS VDD VDD C dsPIC33 VDD 0.1 F Ceramic VSS VSS AVSS VDD AVDD 0.1 F Ceramic VDD 0.1 F Ceramic 0.1 F Ceramic As an option, instead of a hard-wired connection, an inductor (L1) can be substituted between VDD and AVDD to improve ADC noise rejection. The inductor impedance should be less than 1 and the inductor capacity greater than 10 mA. (i.e., ADC Conversion Rate/2) 2 1 L = ---------------------- 2f C 2.2.1 BULK CAPACITORS On boards with power traces running longer than six inches in length, it is suggested to use a bulk capacitor for integrated circuits, including DSCs, to supply a local power source. The value of the bulk capacitor should be determined based on the trace resistance that connects the power supply source to the device and the maximum current drawn by the device in the application. In other words, select the bulk capacitor so that it meets the acceptable voltage sag at the device. Typical values range from 4.7 F to 47 F. DS70005349C-page 24 pin provides two specific device * Device Reset * Device Programming and Debugging. For example, as shown in Figure 2-2, it is recommended that the capacitor, C, be isolated from the MCLR pin during programming and debugging operations. FIGURE 2-2: EXAMPLE OF MCLR PIN CONNECTIONS VDD Where: F CNV f = -------------2 1 f = ---------------------- 2 LC The MCLR functions: Place the components, as shown in Figure 2-2, within one-quarter inch (6 mm) from the MCLR pin. L1(1) Note 1: Master Clear (MCLR) Pin During device programming and debugging, the resistance and capacitance that can be added to the pin must be considered. Device programmers and debuggers drive the MCLR pin. Consequently, specific voltage levels (VIH and VIL) and fast signal transitions must not be adversely affected. Therefore, specific values of R and C will need to be adjusted based on the application and PCB requirements. MCLR VSS 2.3 R(1) R1(2) MCLR JP dsPIC33 C Note 1: R 10 k is recommended. A suggested starting value is 10 k. Ensure that the MCLR pin VIH and VIL specifications are met. 2: R1 470 will limit any current flowing into MCLR from the external capacitor, C, in the event of MCLR pin breakdown due to Electrostatic Discharge (ESD) or Electrical Overstress (EOS). Ensure that the MCLR pin VIH and VIL specifications are met. 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 2.4 ICSP Pins The PGCx and PGDx pins are used for ICSP and debugging purposes. It is recommended to keep the trace length between the ICSP connector and the ICSP pins on the device as short as possible. If the ICSP connector is expected to experience an ESD event, a series resistor is recommended, with the value in the range of a few tens of Ohms, not to exceed 100 Ohms. Pull-up resistors, series diodes and capacitors on the PGCx and PGDx pins are not recommended as they will interfere with the programmer/debugger communications to the device. If such discrete components are an application requirement, they should be removed from the circuit during programming and debugging. Alternatively, refer to the AC/DC characteristics and timing requirements information in the respective device Flash programming specification for information on capacitive loading limits and pin Voltage Input High (VIH) and Voltage Input Low (VIL) requirements. Ensure that the "Communication Channel Select" (i.e., PGCx/PGDx pins) programmed into the device matches the physical connections for the ICSP to PICkitTM 3, MPLAB(R) ICD 3 or MPLAB REAL ICETM emulator. For more information on MPLAB ICD 2, MPLAB ICD 3 and REAL ICE emulator connection requirements, refer to the following documents that are available on the Microchip website. * "Using MPLAB(R) ICD 3 In-Circuit Debugger" (poster) (DS51765) * "Development Tools Design Advisory" (DS51764) * "MPLAB(R) REAL ICETM In-Circuit Emulator User's Guide" (DS51616) * "Using MPLAB(R) REAL ICETM In-Circuit Emulator" (poster) (DS51749) 2017-2018 Microchip Technology Inc. 2.5 External Oscillator Pins Many DSCs have options for at least two oscillators: a high-frequency Primary Oscillator (POSC) and a low-frequency Secondary Oscillator (SOSC). For details, see Section 9.2 "Primary Oscillator (POSC)". The oscillator circuit should be placed on the same side of the board as the device. Also, place the oscillator circuit close to the respective oscillator pins, not exceeding one-half inch (12 mm) distance between them. The load capacitors should be placed next to the oscillator itself, on the same side of the board. Use a grounded copper pour around the oscillator circuit to isolate them from surrounding circuits. The grounded copper pour should be routed directly to the MCU ground. Do not run any signal traces or power traces inside the ground pour. Also, if using a two-sided board, avoid any traces on the other side of the board where the crystal is placed. A suggested layout is shown in Figure 2-3. FIGURE 2-3: SUGGESTED PLACEMENT OF THE OSCILLATOR CIRCUIT Main Oscillator Guard Ring Guard Trace Oscillator Pins DS70005349C-page 25 dsPIC33CK256MP508 FAMILY 2.6 Oscillator Value Conditions on Device Start-up 2.8 * Power Factor Correction (PFC): - Interleaved PFC - Critical Conduction PFC - Bridgeless PFC * DC/DC Converters: - Buck, Boost, Forward, Flyback, Push-Pull - Half/Full-Bridge - Phase-Shift Full-Bridge - Resonant Converters * DC/AC: - Half/Full-Bridge Inverter - Resonant Inverter * Motor Control - BLDC - PMSM - SR - ACIM If the PLL of the target device is enabled and configured for the device start-up oscillator, the maximum oscillator source frequency must be limited to a certain frequency (see Section 9.0 "Oscillator with High-Frequency PLL") to comply with device PLL start-up conditions. This means that if the external oscillator frequency is outside this range, the application must start up in the FRC mode first. The default PLL settings after a POR with an oscillator frequency outside this range will violate the device operating speed. Once the device powers up, the application firmware can initialize the PLL SFRs, CLKDIV and PLLFBD, to a suitable value, and then perform a clock switch to the Oscillator + PLL clock source. Note that clock switching must be enabled in the device Configuration Word. 2.7 Targeted Applications Unused I/Os Examples of typical application connections are shown in Figure 2-4 through Figure 2-6. Unused I/O pins should be configured as outputs and driven to a logic low state. Alternatively, connect a 1k to 10k resistor between VSS and unused pins, and drive the output to logic low.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "dsPIC33E Enhanced CPU" (DS70005158) in the "dsPIC33/ PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The dsPIC33CK256MP508 family CPU has a 16-bit (data) modified Harvard architecture with an enhanced instruction set, including significant support for Digital Signal Processing (DSP). The CPU has a 24-bit instruction word with a variable length opcode field. The Program Counter (PC) is 23 bits wide and addresses up to 4M x 24 bits of user program memory space. An instruction prefetch mechanism helps maintain throughput and provides predictable execution. Most instructions execute in a single-cycle effective execution rate, with the exception of instructions that change the program flow, the double-word move (MOV.D) instruction, PSV accesses and the table instructions. Overhead-free program loop constructs are supported using the DO and REPEAT instructions, both of which are interruptible at any point. 3.1 Registers The dsPIC33CK256MP508 devices have sixteen, 16-bit Working registers in the programmer's model. Each of the Working registers can act as a Data, Address or Address Offset register. The 16th Working register (W15) operates as a Software Stack Pointer for interrupts and calls. In addition, the dsPIC33CK256MP508 devices include four Alternate Working register sets, which consist of W0 through W14. The Alternate Working registers can be made persistent to help reduce the saving and restoring of register content during Interrupt Service Routines (ISRs). The Alternate Working registers can be assigned to a specific Interrupt Priority Level (IPL1 through IPL6) by configuring the CTXTx<2:0> bits in the FALTREG Configuration register. The Alternate Working registers can also be accessed manually by using the CTXTSWP instruction. The CCTXI<2:0> and MCTXI<2:0> bits in the CTXTSTAT register can be used to identify the current, and most recent, manually selected Working register sets. 2017-2018 Microchip Technology Inc. 3.2 Instruction Set The instruction set for dsPIC33CK256MP508 devices has two classes of instructions: the MCU class of instructions and the DSP class of instructions. These two instruction classes are seamlessly integrated into the architecture and execute from a single execution unit. The instruction set includes many addressing modes and was designed for optimum C compiler efficiency. 3.3 Data Space Addressing The base Data Space can be addressed as up to 4K words or 8 Kbytes, and is split into two blocks, referred to as X and Y data memory. Each memory block has its own independent Address Generation Unit (AGU). The MCU class of instructions operates solely through the X memory AGU, which accesses the entire memory map as one linear Data Space. Certain DSP instructions operate through the X and Y AGUs to support dual operand reads, which splits the data address space into two parts. The X and Y Data Space boundary is device-specific. The upper 32 Kbytes of the Data Space memory map can optionally be mapped into Program Space (PS) at any 16K program word boundary. The program-to-Data Space mapping feature, known as Program Space Visibility (PSV), lets any instruction access Program Space as if it were Data Space. Refer to "Data Memory" (DS70595) in the "dsPIC33/PIC24 Family Reference Manual" for more details on PSV and table accesses. On dsPIC33CK256MP508 family devices, overheadfree circular buffers (Modulo Addressing) are supported in both X and Y address spaces. The Modulo Addressing removes the software boundary checking overhead for DSP algorithms. The X AGU Circular Addressing can be used with any of the MCU class of instructions. The X AGU also supports BitReversed Addressing to greatly simplify input or output data re-ordering for radix-2 FFT algorithms. 3.4 Addressing Modes The CPU supports these addressing modes: * * * * * * Inherent (no operand) Relative Literal Memory Direct Register Direct Register Indirect Each instruction is associated with a predefined addressing mode group, depending upon its functional requirements. As many as six addressing modes are supported for each instruction.

DS70005349C-page 37 dsPIC33CK256MP508 FAMILY 3.4.4 ARITHMETIC LOGIC UNIT (ALU) The dsPIC33CK256MP508 family ALU is 16 bits wide and is capable of addition, subtraction, bit shifts and logic operations. Unless otherwise mentioned, arithmetic operations are two's complement in nature. Depending on the operation, the ALU can affect the values of the Carry (C), Zero (Z), Negative (N), Overflow (OV) and Digit Carry (DC) Status bits in the SR register. The C and DC Status bits operate as Borrow and Digit Borrow bits, respectively, for subtraction operations. The ALU can perform 8-bit or 16-bit operations, depending on the mode of the instruction that is used. Data for the ALU operation can come from the W register array or data memory, depending on the addressing mode of the instruction. Likewise, output data from the ALU can be written to the W register array or a data memory location. Refer to the "16-Bit MCU and DSC Programmer's Reference Manual" (DS70000157) for information on the SR bits affected by each instruction. The core CPU incorporates hardware support for both multiplication and division. This includes a dedicated hardware multiplier and support hardware for 16-bit divisor division. 3.4.4.1 Multiplier Using the high-speed, 17-bit x 17-bit multiplier, the ALU supports unsigned, signed or mixed-sign operation in several MCU multiplication modes: * * * * * * * 16-bit x 16-bit signed 16-bit x 16-bit unsigned 16-bit signed x 5-bit (literal) unsigned 16-bit signed x 16-bit unsigned 16-bit unsigned x 5-bit (literal) unsigned 16-bit unsigned x 16-bit signed 8-bit unsigned x 8-bit unsigned 3.4.4.2 Divider The divide block supports 32-bit/16-bit and 16-bit/16-bit signed and unsigned integer divide operations with the following data sizes: * * * * 3.4.5 DSP ENGINE The DSP engine consists of a high-speed 17-bit x 17-bit multiplier, a 40-bit barrel shifter and a 40-bit adder/ subtracter (with two target accumulators, round and saturation logic). The DSP engine can also perform inherent accumulatorto-accumulator operations that require no additional data. These instructions are, ADD, SUB, NEG, MIN and MAX. The DSP engine has options selected through bits in the CPU Core Control register (CORCON), as listed below: * Fractional or integer DSP multiply (IF) * Signed, unsigned or mixed-sign DSP multiply (USx) * Conventional or convergent rounding (RND) * Automatic saturation on/off for ACCA (SATA) * Automatic saturation on/off for ACCB (SATB) * Automatic saturation on/off for writes to data memory (SATDW) * Accumulator Saturation mode selection (ACCSAT) TABLE 3-2: Instruction CLR DSP INSTRUCTIONS SUMMARY Algebraic Operation ACC Write-Back Yes A=0 2 ED A = (x - y) No EDAC A = A + (x - y)2 No MAC A = A + (x * y) Yes MAC A = A + x2 No MOVSAC No change in A Yes MPY A=x*y No 2 No MPY A=x MPY.N A=-x*y No MSC A=A-x*y Yes 32-bit signed/16-bit signed divide 32-bit unsigned/16-bit unsigned divide 16-bit signed/16-bit signed divide 16-bit unsigned/16-bit unsigned divide The 16-bit signed and unsigned DIV instructions can specify any W register for both the 16-bit divisor (Wn) and any W register (aligned) pair (W(m + 1):Wm) for the 32-bit dividend. The divide algorithm takes one cycle per bit of divisor, so both 32-bit/16-bit and 16-bit/ 16-bit instructions take the same number of cycles to execute. There are additional instructions: DIV2 and DIVF2. Divide instructions will complete in six cycles.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "dsPIC33E/PIC24E Program Memory" (DS70000613) in the "dsPIC33/ PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The dsPIC33CK256MP508 family architecture features separate program and data memory spaces, and buses. This architecture also allows the direct access of program memory from the Data Space (DS) during code execution. FIGURE 4-1: 4.1 Program Address Space The program address memory space of the dsPIC33CK256MP508 family devices is 4M instructions. The space is addressable by a 24-bit value derived either from the 23-bit PC during program execution, or from table operation or Data Space remapping, as described in Section 4.4.5 "Interfacing Program and Data Memory Spaces". User application access to the program memory space is restricted to the lower half of the address range (0x000000 to 0x7FFFFF). The exception is the use of TBLRD operations, which use TBLPAG<7> to permit access to calibration data and Device ID sections of the configuration memory space. The program memory maps for dsPIC33CK256MP508 devices are shown in Figure 4-1 through Figure 4-5.

DS70005349C-page 41 dsPIC33CK256MP508 FAMILY 4.1.1 PROGRAM MEMORY ORGANIZATION 4.1.2 All dsPIC33CK256MP508 family devices reserve the addresses between 0x000000 and 0x000200 for hardcoded program execution vectors. A hardware Reset vector is provided to redirect code execution from the default value of the PC on device Reset to the actual start of code. A GOTO instruction is programmed by the user application at address, 0x000000, of Flash memory, with the actual address for the start of code at address, 0x000002, of Flash memory. The program memory space is organized in wordaddressable blocks. Although it is treated as 24 bits wide, it is more appropriate to think of each address of the program memory as a lower and upper word, with the upper byte of the upper word being unimplemented. The lower word always has an even address, while the upper word has an odd address (Figure 4-6). Program memory addresses are always word-aligned on the lower word, and addresses are incremented or decremented, by two, during code execution. This arrangement provides compatibility with data memory space addressing and makes data in the program memory space accessible.

The UDID cannot be erased by a bulk erase command or any other user-accessible means. This feature allows for manufacturing traceability of Microchip Technology devices in applications where this is a requirement. It may also be used by the application manufacturer for any number of things that may require unique identification, such as: * Tracking the device * Unique serial number * Unique security key The UDID comprises five 24-bit program words. When taken together, these fields form a unique 120-bit identifier. The UDID is stored in five read-only locations, located between 0x801200 and 0x801208 in the device configuration space. Table 4-1 lists the addresses of the identifier words and shows their contents TABLE 4-1: 4.2 UDID ADDRESSES UDID Address Description UDID1 0x801200 UDID Word 1 UDID2 0x801202 UDID Word 2 UDID3 0x801204 UDID Word 3 UDID4 0x801206 UDID Word 4 UDID5 0x801208 UDID Word 5 Data Address Space The dsPIC33CK256MP508 family CPU has a separate 16-bit wide data memory space. The Data Space is accessed using separate Address Generation Units (AGUs) for read and write operations. The data memory maps are shown in Figure 4-7, Figure 4-8 and Figure 4-9. All Effective Addresses (EAs) in the data memory space are 16 bits wide and point to bytes within the Data Space. This arrangement gives a base Data Space address range of 64 Kbytes or 32K words. The lower half of the data memory space (i.e., when EA<15> = 0) is used for implemented memory addresses, while the upper half (EA<15> = 1) is reserved for the Program Space Visibility (PSV). The dsPIC33CK256MP508 family devices implement up to 16 Kbytes of data memory. If an EA points to a location outside of this area, an all-zero word or byte is returned. 2017-2018 Microchip Technology Inc. 4.2.1 DATA SPACE WIDTH The data memory space is organized in byteaddressable, 16-bit wide blocks. Data is aligned in data memory and registers as 16-bit words, but all Data Space EAs resolve to bytes. The Least Significant Bytes (LSBs) of each word have even addresses, while the Most Significant Bytes (MSBs) have odd addresses. 4.2.2 DATA MEMORY ORGANIZATION AND ALIGNMENT To maintain backward compatibility with PIC(R) MCU devices and improve Data Space memory usage efficiency, the dsPIC33CK256MP508 family instruction set supports both word and byte operations. As a consequence of byte accessibility, all Effective Address calculations are internally scaled to step through wordaligned memory. For example, the core recognizes that Post-Modified Register Indirect Addressing mode [Ws++] results in a value of Ws + 1 for byte operations and Ws + 2 for word operations. A data byte read, reads the complete word that contains the byte, using the LSb of any EA to determine which byte to select. The selected byte is placed onto the LSB of the data path. That is, data memory and registers are organized as two parallel, byte-wide entities with shared (word) address decode, but separate write lines. Data byte writes only write to the corresponding side of the array or register that matches the byte address. All word accesses must be aligned to an even address. Misaligned word data fetches are not supported, so care must be taken when mixing byte and word operations, or translating from 8-bit MCU code. If a misaligned read or write is attempted, an address error trap is generated. If the error occurred on a read, the instruction underway is completed. If the error occurred on a write, the instruction is executed but the write does not occur. In either case, a trap is then executed, allowing the system and/or user application to examine the machine state prior to execution of the address Fault. All byte loads into any W register are loaded into the LSB; the MSB is not modified. A Sign-Extend (SE) instruction is provided to allow user applications to translate 8-bit signed data to 16-bit signed values. Alternatively, for 16-bit unsigned data, user applications can clear the MSB of any W register by executing a Zero-Extend (ZE) instruction on the appropriate address. DS70005349C-page 43 dsPIC33CK256MP508 FAMILY 4.2.3 SFR SPACE The first four Kbytes of the Near Data Space, from 0x0000 to 0x0FFF, is primarily occupied by Special Function Registers (SFRs). These are used by the dsPIC33CK256MP508 family core and peripheral modules for controlling the operation of the device. SFRs are distributed among the modules that they control and are generally grouped together by module. Much of the SFR space contains unused addresses; these are read as `0'. Note: 4.2.4 NEAR DATA SPACE The 8-Kbyte area, between 0x0000 and 0x1FFF, is referred to as the Near Data Space. Locations in this space are directly addressable through a 13-bit absolute address field within all memory direct instructions. Additionally, the whole Data Space is addressable using MOV instructions, which support Memory Direct Addressing mode with a 16-bit address field, or by using Indirect Addressing mode using a Working register as an Address Pointer. The actual set of peripheral features and interrupts varies by the device. Refer to the corresponding device tables and pinout diagrams for device-specific information.

DS70005349C-page 47 dsPIC33CK256MP508 FAMILY 4.2.5 X AND Y DATA SPACES FIGURE 4-10: The dsPIC33CK256MP508 family core has two Data Spaces, X and Y. These Data Spaces can be considered either separate (for some DSP instructions) or as one unified linear address range (for MCU instructions). The Data Spaces are accessed using two Address Generation Units (AGUs) and separate data paths. This feature allows certain instructions to concurrently fetch two words from RAM, thereby enabling efficient execution of DSP algorithms, such as Finite Impulse Response (FIR) filtering and Fast Fourier Transform (FFT). POR BISTDIS (FPOR<6>) Both the X and Y Data Spaces support Modulo Addressing mode for all instructions, subject to addressing mode restrictions. Bit-Reversed Addressing mode is only supported for writes to X Data Space. All data memory writes, including in DSP instructions, view Data Space as combined X and Y address space. The boundary between the X and Y Data Spaces is device-dependent and is not user-programmable. 4.2.6 BIST OVERVIEW The dsPIC33CK256MP508 family features a data memory Built-In Self-Test (BIST) that has the option to be run at start-up or run time. The memory test checks that all memory locations are functional and provides a pass/fail status of the RAM that can be used by software to take action if needed. If a failure is reported, the specific location(s) are not identified. The MBISTCON register (Register 4-1) contains control and status bits for BIST operation. The MBISTDONE bit (MBISTCON<7>) indicates if a BIST was run since the last Reset and the MBISTSTAT bit (MBISTCON<4>) provides the pass fail result. 4.2.7 1 0 The X Data Space is used by all instructions and supports all addressing modes. X Data Space has separate read and write data buses. The X read data bus is the read data path for all instructions that view Data Space as combined X and Y address space. It is also the X data prefetch path for the dual operand DSP instructions (MAC class). The Y Data Space is used in concert with the X Data Space by the MAC class of instructions (CLR, ED, EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to provide two concurrent data read paths. BIST FLOWCHART BIST Code Execution 4.2.8 BIST AT RUN TIME A BIST test can be requested to run on subsequent device Resets at any time. A BIST will corrupt all of the RAM contents, including the Stack Pointer, and requires a subsequent Reset. The system should be prepared for a Reset before a BIST is performed. The BIST is invoked by setting the MBISTEN bit (MBISTCON<0>) and executing a Reset. The MBISTCON register is protected against accidental writes and requires an unlock sequence prior to writing. Only one bit can be set per unlock sequence. The procedure for a run-time BIST is as follows: 1. 2. 3. 4. 5. 6. Execute the unlock sequence by consecutively writing 0x55 and 0xAA to the NVMKEY register. Write 0x0001 to the MBISTCON SFR. Execute a software RESET command. Verify a Software Reset has occurred by reading SWR (RCON<6>) (optional). Verify that the MBISTDONE bit is set. Take action depending on test result indicated by MBISTSTAT. BIST AT START-UP The BIST can be configured to automatically run on a POR type Reset, as shown in Figure 4-10. By default, when BISTDIS (FPOR<6>) = 1, the BIST is disabled and will not be part of device start-up. If the BISTDIS bit is cleared during device programming, the BIST will run after all Configuration registers have been loaded and before code execution begins. BIST will always run on FRC+PLL with PLL settings resulting in a 125 MHz clock rate. DS70005349C-page 48 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 4.2.8.1 Fault Simulation 1. A mechanism is available to simulate a BIST failure to allow testing of Fault handling software. When the FLTINJ bit is set during a run-time BIST, the MBISTSTAT bit will be set regardless of the test result. The procedure for a BIST Fault simulation is as follows: REGISTER 4-1: 2. 3. 4. 5. 6. Execute the unlock sequence by consecutively writing 0x55 and 0xAA to the NVMKEY register. Set the MBISTEN bit (MBISTCON<0>). Execute 2nd unlock sequence by consecutively writing 0x55 and 0xAA to the NVMKEY register. Set the FLTINJ bit (MBISTCON<8>). Execute a software RESET command. Verify the MBISTDONE, MBSITSTAT and FLTINJ bits are all set.

DS70005349C-page 64 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 4.4.1 PAGED MEMORY SCHEME The paged memory scheme provides access to multiple 32-Kbyte windows in the PSV memory. The Data Space Read Page (DSRPAG) register, in combination with the upper half of the Data Space address, can provide up to 8 Mbytes of PSV address space. The paged data memory space is shown in Figure 4-12. The dsPIC33CK256MP508 architecture extends the available Data Space through a paging scheme, which allows the available Data Space to be accessed using MOV instructions in a linear fashion for pre- and post-modified Effective Addresses (EAs). The upper half of the base Data Space address is used in conjunction with the Data Space Read Page (DSRPAG) register to form the Program Space Visibility (PSV) address. The Program Space (PS) can be accessed with a DSRPAG of 0x200 or greater. Only reads from PS are supported using the DSRPAG. The Data Space Read Page (DSRPAG) register is located in the SFR space. Construction of the PSV address is shown in Figure 4-11. When DSRPAG<9> = 1 and the base address bit, EA<15> = 1, the DSRPAG<8:0> bits are concatenated onto EA<14:0> to form the 24-bit PSV read address.

An overflow or underflow of the EA in the PSV pages can occur at the page boundaries when: * The initial address, prior to modification, addresses the PSV page * The EA calculation uses Pre- or Post-Modified Register Indirect Addressing; however, this does not include Register Offset Addressing In general, when an overflow is detected, the DSRPAG register is incremented and the EA<15> bit is set to keep the base address within the PSV window. When an underflow is detected, the DSRPAG register is decremented and the EA<15> bit is set to keep the base TABLE 4-17: O, Read [++Wn] or [Wn++] U, Read U, Read U, Read [--Wn] or [Wn--] Legend: Note 1: 2: 3: 4: Exceptions to the operation described above arise when entering and exiting the boundaries of Page 0 and PSV spaces. Table 4-17 lists the effects of overflow and underflow scenarios at different boundaries.

An EDS access, with DSRPAG = 0x000, will generate an address error trap. Only reads from PS are supported using DSRPAG. Pseudolinear Addressing is not supported for large offsets. 2017-2018 Microchip Technology Inc. DS70005349C-page 67 dsPIC33CK256MP508 FAMILY 4.4.1.1 Extended X Data Space The lower portion of the base address space range, between 0x0000 and 0x7FFF, is always accessible, regardless of the contents of the Data Space Read Page register. It is indirectly addressable through the register indirect instructions. It can be regarded as being located in the default EDS Page 0 (i.e., EDS address range of 0x000000 to 0x007FFF with the base address bit, EA<15> = 0, for this address range). However, Page 0 cannot be accessed through the upper 32 Kbytes, 0x8000 to 0xFFFF, of base Data Space in combination with DSRPAG = 0x00. Consequently, DSRPAG is initialized to 0x001 at Reset. Note 1: DSRPAG should not be used to access Page 0. An EDS access with DSRPAG set to 0x000 will generate an address error trap. When the PC is pushed onto the stack, PC<15:0> are pushed onto the first available stack word, then PC<22:16> are pushed into the second available stack location. For a PC push during any CALL instruction, the MSB of the PC is zero-extended before the push, as shown in Figure 4-13. During exception processing, the MSB of the PC is concatenated with the lower eight bits of the CPU STATUS Register, SR. This allows the contents of SRL to be preserved automatically during interrupt processing. Note 1: To maintain system Stack Pointer (W15) coherency, W15 is never subject to (EDS) paging, and is therefore, restricted to an address range of 0x0000 to 0xFFFF. The same applies to the W14 when used as a Stack Frame Pointer (SFA = 1). 2: As the stack can be placed in, and can access X and Y spaces, care must be taken regarding its use, particularly with regard to local automatic variables in a C development environment 2: Clearing the DSRPAG in software has no effect. 4.4.1.2 Software Stack The W15 register serves as a dedicated Software Stack Pointer (SSP), and is automatically modified by exception processing, subroutine calls and returns; however, W15 can be referenced by any instruction in the same manner as all other W registers. This simplifies reading, writing and manipulating the Stack Pointer (for example, creating stack frames). Note: To protect against misaligned stack accesses, W15<0> is fixed to `0' by the hardware. FIGURE 4-13: 0x0000 CALL STACK FRAME 15 0 CALL SUBR Stack Grows Toward Higher Address The remaining PSV pages are only accessible using the DSRPAG register in combination with the upper 32 Kbytes, 0x8000 to 0xFFFF, of the base address, where the base address bit, EA<15> = 1. PC<15:1> W15 (before CALL) b`000000000' PC<22:16> W15 (after CALL) W15 is initialized to 0x1000 during all Resets. This address ensures that the SSP points to valid RAM in all dsPIC33CK256MP508 devices and permits stack availability for non-maskable trap exceptions. These can occur before the SSP is initialized by the user software. You can reprogram the SSP during initialization to any location within Data Space. The Software Stack Pointer always points to the first available free word and fills the software stack, working from lower toward higher addresses. Figure 4-13 illustrates how it pre-decrements for a stack pop (read) and post-increments for a stack push (writes).

The addressing modes provided in the MAC class of instructions differ from those in the other instruction types. 4.4.2.1 File Register Instructions Most file register instructions use a 13-bit address field (f) to directly address data present in the first 8192 bytes of data memory (Near Data Space). Most file register instructions employ a Working register, W0, which is denoted as WREG in these instructions. The destination is typically either the same file register or WREG (with the exception of the MUL instruction), which writes the result to a register or register pair. The MOV instruction allows additional flexibility and can access the entire Data Space. TABLE 4-18: 4.4.2.2 MCU Instructions The three-operand MCU instructions are of the form: Operand 3 = Operand 1 Operand 2 where Operand 1 is always a Working register (that is, the addressing mode can only be Register Direct), which is referred to as Wb. Operand 2 can be a W register fetched from data memory or a 5-bit literal. The result location can either be a W register or a data memory location. The following addressing modes are supported by MCU instructions: * * * * * Register Direct Register Indirect Register Indirect Post-Modified Register Indirect Pre-Modified 5-Bit or 10-Bit Literal Note: Not all instructions support all the addressing modes given above. Individual instructions can support different subsets of these addressing modes. FUNDAMENTAL ADDRESSING MODES SUPPORTED Addressing Mode File Register Direct Description The address of the file register is specified explicitly. Register Direct The contents of a register are accessed directly. Register Indirect The contents of Wn form the Effective Address (EA). Register Indirect Post-Modified The contents of Wn form the EA. Wn is post-modified (incremented or decremented) by a constant value. Register Indirect Pre-Modified Wn is pre-modified (incremented or decremented) by a signed constant value to form the EA. Register Indirect with Register Offset The sum of Wn and Wb forms the EA. (Register Indexed) Register Indirect with Literal Offset 2017-2018 Microchip Technology Inc. The sum of Wn and a literal forms the EA. DS70005349C-page 69 dsPIC33CK256MP508 FAMILY 4.4.2.3 Move and Accumulator Instructions Move instructions, and the DSP accumulator class of instructions, provide a greater degree of addressing flexibility than other instructions. In addition to the addressing modes supported by most MCU instructions, move and accumulator instructions also support Register Indirect with Register Offset Addressing mode, also referred to as Register Indexed mode. Note: For the MOV instructions, the addressing mode specified in the instruction can differ for the source and destination EA. However, the 4-bit Wb (Register Offset) field is shared by both source and destination (but typically only used by one). 4.4.2.4 The dual source operand DSP instructions (CLR, ED, EDAC, MAC, MPY, MPY.N, MOVSAC and MSC), also referred to as MAC instructions, use a simplified set of addressing modes to allow the user application to effectively manipulate the Data Pointers through register indirect tables. The two-source operand prefetch registers must be members of the set {W8, W9, W10, W11}. For data reads, W8 and W9 are always directed to the X RAGU, and W10 and W11 are always directed to the Y AGU. The Effective Addresses generated (before and after modification) must therefore, be valid addresses within X Data Space for W8 and W9, and Y Data Space for W10 and W11. In summary, the following addressing modes are supported by move and accumulator instructions: * * * * * * * * Register Direct Register Indirect Register Indirect Post-Modified Register Indirect Pre-Modified Register Indirect with Register Offset (Indexed) Register Indirect with Literal Offset 8-Bit Literal 16-Bit Literal Note: Not all instructions support all the addressing modes given above. Individual instructions may support different subsets of these addressing modes. DS70005349C-page 70 MAC Instructions Note: Register Indirect with Register Offset Addressing mode is available only for W9 (in X space) and W11 (in Y space). In summary, the following addressing modes are supported by the MAC class of instructions: * * * * * Register Indirect Register Indirect Post-Modified by 2 Register Indirect Post-Modified by 4 Register Indirect Post-Modified by 6 Register Indirect with Register Offset (Indexed) 4.4.2.5 Other Instructions Besides the addressing modes outlined previously, some instructions use literal constants of various sizes. For example, BRA (branch) instructions use 16-bit signed literals to specify the branch destination directly, whereas the DISI instruction uses a 14-bit unsigned literal field. In some instructions, such as ULNK, the source of an operand or result is implied by the opcode itself. Certain operations, such as a NOP, do not have any operands. 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 4.4.3 MODULO ADDRESSING 4.4.3.1 Modulo Addressing mode is a method of providing an automated means to support circular data buffers using hardware. The objective is to remove the need for software to perform data address boundary checks when executing tightly looped code, as is typical in many DSP algorithms. Start and End Address The Modulo Addressing scheme requires that a starting and ending address be specified and loaded into the 16-bit Modulo Buffer Address registers: XMODSRT, XMODEND, YMODSRT and YMODEND (see Table 4-2). Note: Y space Modulo Addressing EA calculations assume word-sized data (LSb of every EA is always clear). Modulo Addressing can operate in either Data or Program Space (since the Data Pointer mechanism is essentially the same for both). One circular buffer can be supported in each of the X (which also provides the pointers into Program Space) and Y Data Spaces. Modulo Addressing can operate on any W Register Pointer. However, it is not advisable to use W14 or W15 for Modulo Addressing since these two registers are used as the Stack Frame Pointer and Stack Pointer, respectively. The length of a circular buffer is not directly specified. It is determined by the difference between the corresponding start and end addresses. The maximum possible length of the circular buffer is 32K words (64 Kbytes). In general, any particular circular buffer can be configured to operate in only one direction, as there are certain restrictions on the buffer start address (for incrementing buffers) or end address (for decrementing buffers), based upon the direction of the buffer. The Modulo and Bit-Reversed Addressing Control register, MODCON<15:0>, contains enable flags, as well as a W register field to specify the W Address registers. The XWM and YWM fields select the registers that operate with Modulo Addressing: The only exception to the usage restrictions is for buffers that have a power-of-two length. As these buffers satisfy the start and end address criteria, they can operate in a Bidirectional mode (that is, address boundary checks are performed on both the lower and upper address boundaries). * If XWM = 1111, X RAGU and X WAGU Modulo Addressing is disabled * If YWM = 1111, Y AGU Modulo Addressing is disabled 4.4.3.2 W Address Register Selection The X Address Space Pointer W (XWM) register, to which Modulo Addressing is to be applied, is stored in MODCON<3:0> (see Table 4.1). Modulo Addressing is enabled for X Data Space when XWM is set to any value other than `1111' and the XMODEN bit is set (MODCON<15>). The Y Address Space Pointer W (YWM) register, to which Modulo Addressing is to be applied, is stored in MODCON<7:4>. Modulo Addressing is enabled for Y Data Space when YWM is set to any value other than `1111' and the YMODEN bit (MODCON<14>) is set.

Address boundaries check for addresses equal to: * The upper boundary addresses for incrementing buffers * The lower boundary addresses for decrementing buffers It is important to realize that the address boundaries check for addresses less than, or greater than, the upper (for incrementing buffers) and lower (for decrementing buffers) boundary addresses (not just equal to). Address changes can, therefore, jump beyond boundaries and still be adjusted correctly. Note: 4.4.4 The modulo corrected Effective Address is written back to the register only when Pre-Modify or Post-Modify Addressing mode is used to compute the Effective Address. When an address offset (such as [W7 + W2]) is used, Modulo Addressing correction is performed, but the contents of the register remain unchanged. BIT-REVERSED ADDRESSING Bit-Reversed Addressing mode is intended to simplify data reordering for radix-2 FFT algorithms. It is supported by the X AGU for data writes only. The modifier, which can be a constant value or register contents, is regarded as having its bit order reversed. The address source and destination are kept in normal order. Thus, the only operand requiring reversal is the modifier. 4.4.4.1 Bit-Reversed Addressing Implementation Bit-Reversed Addressing mode is enabled in any of these situations: * BWMx bits (W register selection) in the MODCON register are any value other than `1111' (the stack cannot be accessed using Bit-Reversed Addressing) * The BREN bit is set in the XBREV register * The addressing mode used is Register Indirect with Pre-Increment or Post-Increment If the length of a bit-reversed buffer is M = 2N bytes, the last `N' bits of the data buffer start address must be zeros. XB<14:0> is the Bit-Reversed Addressing modifier, or `pivot point', which is typically a constant. In the case of an FFT computation, its value is equal to half of the FFT data buffer size. Note: All bit-reversed EA calculations assume word-sized data (LSb of every EA is always clear). The XB value is scaled accordingly to generate compatible (byte) addresses. When enabled, Bit-Reversed Addressing is executed only for Register Indirect with Pre-Increment or PostIncrement Addressing and word-sized data writes. It does not function for any other addressing mode or for byte-sized data and normal addresses are generated instead. When Bit-Reversed Addressing is active, the W Address Pointer is always added to the address modifier (XB) and the offset associated with the Register Indirect Addressing mode is ignored. In addition, as word-sized data is a requirement, the LSb of the EA is ignored (and always clear). Note: Modulo Addressing and Bit-Reversed Addressing can be enabled simultaneously using the same W register, but BitReversed Addressing operation will always take precedence for data writes when enabled. If Bit-Reversed Addressing has already been enabled by setting the BREN (XBREV<15>) bit, a write to the XBREV register should not be immediately followed by an indirect read operation using the W register that has been designated as the Bit-Reversed Pointer.

DS70005349C-page 73 dsPIC33CK256MP508 FAMILY 4.4.5 INTERFACING PROGRAM AND DATA MEMORY SPACES Table instructions allow an application to read or write to small areas of the program memory. This capability makes the method ideal for accessing data tables that need to be updated periodically. It also allows access to all bytes of the program word. The remapping method allows an application to access a large block of data on a read-only basis, which is ideal for look-ups from a large table of static data. The application can only access the least significant word of the program word. The dsPIC33CK256MP508 family architecture uses a 24-bit wide Program Space (PS) and a 16-bit wide Data Space (DS). The architecture is also a modified Harvard scheme, meaning that data can also be present in the Program Space. To use this data successfully, it must be accessed in a way that preserves the alignment of information in both spaces. Aside from normal execution, the architecture of the dsPIC33CK256MP508 family devices provides two methods by which Program Space can be accessed during operation: * Using table instructions to access individual bytes or words anywhere in the Program Space * Remapping a portion of the Program Space into the Data Space (Program Space Visibility) TABLE 4-20: PROGRAM SPACE ADDRESS CONSTRUCTION Program Space Address Access Space Access Type <23> <22:16> Instruction Access (Code Execution) User TBLRD/TBLWT (Byte/Word Read/Write) User TBLPAG<7:0> Configuration TBLPAG<7:0> <15> 0xxx xxxx xxxx 0xxx xxxx 1xxx xxxx FIGURE 4-16: <14:1> PC<22:1> 0 <0> 0 xxxx xxxx xxx0 Data EA<15:0> xxxx xxxx xxxx xxxx Data EA<15:0> xxxx xxxx xxxx xxxx DATA ACCESS FROM PROGRAM SPACE ADDRESS GENERATION Program Counter(1) Program Counter 0 0 23 Bits EA Table Operations(2) 1/0 1/0 TBLPAG 8 Bits 16 Bits 24 Bits User/Configuration Space Select Note 1: 2: Byte Select The Least Significant bit (LSb) of Program Space addresses is always fixed as `0' to maintain word alignment of data in the Program and Data Spaces. Table operations are not required to be word-aligned. Table Read operations are permitted in the configuration memory space. DS70005349C-page 74 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 4.4.5.1 Data Access from Program Memory Using Table Instructions The TBLRDL and TBLWTL instructions offer a direct method of reading or writing the lower word of any address within the Program Space without going through Data Space. The TBLRDH and TBLWTH instructions are the only method to read or write the upper 8 bits of a Program Space word as data. The PC is incremented by two for each successive 24-bit program word. This allows program memory addresses to directly map to Data Space addresses. Program memory can thus be regarded as two 16-bit wide word address spaces, residing side by side, each with the same address range. TBLRDL and TBLWTL access the space that contains the least significant data word. TBLRDH and TBLWTH access the space that contains the upper data byte. Two table instructions are provided to move byte or word-sized (16-bit) data to and from Program Space. Both function as either byte or word operations. * TBLRDL (Table Read Low): - In Word mode, this instruction maps the lower word of the Program Space location (P<15:0>) to a data address (D<15:0>) - In Byte mode, either the upper or lower byte of the lower program word is mapped to the lower byte of a data address. The upper byte is selected when Byte Select is `1'; the lower byte is selected when it is `0'. FIGURE 4-17: * TBLRDH (Table Read High): - In Word mode, this instruction maps the entire upper word of a program address (P<23:16>) to a data address. The `phantom' byte (D<15:8>) is always `0'. - In Byte mode, this instruction maps the upper or lower byte of the program word to D<7:0> of the data address in the TBLRDL instruction. The data is always `0' when the upper `phantom' byte is selected (Byte Select = 1). In a similar fashion, two table instructions, TBLWTH and TBLWTL, are used to write individual bytes or words to a Program Space address. The details of their operation are explained in Section 5.0 "Flash Program Memory". For all table operations, the area of program memory space to be accessed is determined by the Table Page register (TBLPAG). TBLPAG covers the entire program memory space of the device, including user application and configuration spaces. When TBLPAG<7> = 0, the table page is located in the user memory space. When TBLPAG<7> = 1, the page is located in configuration space.

This also allows the most recent firmware or a custom firmware to be programmed. Note 1: This data sheet summarizes the features of the dsPIC33CK256MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Dual Partition Flash Program Memory" (DS70005156) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). Enhanced In-Circuit Serial Programming uses an on-board bootloader, known as the Program Executive, to manage the programming process. Using an SPI data frame format, the Program Executive can erase, program and verify program memory. For more information on Enhanced ICSP, see the device programming specification. RTSP is accomplished using TBLRD (Table Read) and TBLWT (Table Write) instructions. With RTSP, the user application can write program memory data with a single program memory word and erase program memory in blocks or `pages' of 1024 instructions (3072 bytes) at a time. 2: Some registers and associated bits described in this section may not be available on all devices. The dsPIC33CK256MP508 family devices contain internal Flash program memory for storing and executing application code. The memory is readable, writable and erasable during normal operation over the entire VDD range. 5.1 Regardless of the method used, all programming of Flash memory is done with the Table Read and Table Write instructions. These allow direct read and write access to the program memory space from the data memory while the device is in normal operating mode. The 24-bit target address in the program memory is formed using bits<7:0> of the TBLPAG register and the Effective Address (EA) from a W register, specified in the table instruction, as shown in Figure 5-1. The TBLRDL and TBLWTL instructions are used to read or write to bits<15:0> of program memory. TBLRDL and TBLWTL can access program memory in both Word and Byte modes. The TBLRDH and TBLWTH instructions are used to read or write to bits<23:16> of program memory. TBLRDH and TBLWTH can also access program memory in Word or Byte mode. Flash memory can be programmed in three ways: * In-Circuit Serial ProgrammingTM (ICSPTM) programming capability * Enhanced In-Circuit Serial Programming (Enhanced ICSP) * Run-Time Self-Programming (RTSP) ICSP allows for a dsPIC33CK256MP508 family device to be serially programmed while in the end application circuit. This is done with a Programming Clock and Programming Data (PGCx/PGDx) line, and three other lines for power (VDD), ground (VSS) and Master Clear (MCLR). This allows customers to manufacture boards with unprogrammed devices and then program the FIGURE 5-1: Table Instructions and Flash Programming ADDRESSING FOR TABLE REGISTERS 24 Bits Using Program Counter Program Counter 0 0 Working Reg EA Using Table Instruction 1/0 TBLPAG Reg 8 Bits User/Configuration Space Select 2017-2018 Microchip Technology Inc. 16 Bits 24-Bit EA Byte Select DS70005349C-page 77 dsPIC33CK256MP508 FAMILY The dsPIC33CK256MP508 family Flash program memory array is organized into rows of 128 instructions or 384 bytes. RTSP allows the user application to erase a single page (eight rows or 1024 instructions) of memory at a time and to program one row at a time. It is possible to program two instructions at a time as well. The page erase and single row write blocks are edge-aligned, from the beginning of program memory, on boundaries of 3072 bytes and 384 bytes, respectively. Table 33-18 in Section 33.0 "Electrical Characteristics" lists the typical erase and programming times. Row programming is performed by loading 384 bytes into data memory and then loading the address of the first byte in that row into the NVMSRCADRL/H register. Once the write has been initiated, the device will automatically load the write latches, and increment the NVMSRCADRL/H and the NVMADR(U) registers until all bytes have been programmed. The RPDF bit (NVMCON<9>) selects the format of the stored data in RAM to be either compressed or uncompressed. See Figure 5-2 for data formatting. Compressed data helps to reduce the amount of required RAM by using the upper byte of the second word for the MSB of the second instruction. The basic sequence for RTSP word programming is to use the TBLWTL and TBLWTH instructions to load two of the 24-bit instructions into the write latches found in configuration memory space. Refer to Figure 4-1 through Figure 4-5 for write latch addresses. Programming is performed by unlocking and setting the control bits in the NVMCON register. All erase and program operations may optionally use the NVM interrupt to signal the successful completion of the operation. For example, when performing Flash write operations on the Inactive Partition in Dual Partition mode, where the CPU remains running, it is necessary to wait for the NVM interrupt before programming the next block of Flash program memory. DS70005349C-page 78 FIGURE 5-2: UNCOMPRESSED/ COMPRESSED FORMAT 15 0 7 LSW1 Increasing Address RTSP Operation 0x00 Even Byte Address MSB1 LSW2 0x00 MSB2 UNCOMPRESSED FORMAT (RPDF = 0) 15 Increasing Address 5.2 0 7 LSW1 MSB2 Even Byte Address MSB1 LSW2 COMPRESSED FORMAT (RPDF = 1) 5.3 Programming Operations A complete programming sequence is necessary for programming or erasing the internal Flash in RTSP mode. The processor stalls (waits) until the programming operation is finished. Setting the WR bit (NVMCON<15>) starts the operation and the WR bit is automatically cleared when the operation is finished. 5.3.1 PROGRAMMING ALGORITHM FOR FLASH PROGRAM MEMORY Programmers can program two adjacent words (24 bits x 2) of Program Flash Memory at a time on every other word address boundary (0x000002, 0x000006, 0x00000A, etc.). To do this, it is necessary to erase the page that contains the desired address of the location the user wants to change. For protection against accidental operations, the write initiate sequence for NVMKEY must be used to allow any erase or program operation to proceed. After the programming command has been executed, the user application must wait for the programming time until programming is complete. The two instructions following the start of the programming sequence should be NOPs. 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 5.3.2 ERROR CORRECTING CODE (ECC) In order to improve program memory performance and durability, these devices include Error Correcting Code (ECC) functionality as an integral part of the Flash memory controller. ECC can determine the presence of single bit errors in program data, including which bit is in error, and correct the data automatically without user intervention. ECC cannot be disabled. When data is written to program memory, ECC generates a 7-bit Hamming code parity value for every two (24-bit) instruction words. The data is stored in blocks of 48 data bits and 7 parity bits; parity data is not memory-mapped and is inaccessible. When the data is read back, the ECC calculates the parity on it and compares it to the previously stored parity value. If a parity mismatch occurs, there are two possible outcomes: * Single bit error has occurred and has been automatically corrected on readback. * Double-bit error has occurred and the read data is not changed. Single bit error occurrence can be identified by the state of the ECCSBEIF (IFS0<13>) bit. An interrupt can be generated when the corresponding interrupt enable bit is set, ECCSBEIE (IEC0<13>). The ECCSTATL register contains the parity information for single bit errors. The SECOUT<7:0> bits field contains the expected calculated SEC parity and the SECIN<7:0> bits contain the actual value from a Flash read operation. The SECSYNDx bits (ECCSTATH<7:0>) indicate the bit position of the single bit error within the 48-bit pair of instruction words. When no error is present, SECINx equals SECOUTx and SECSYNDx is zero. 5.3.3 ECC FAULT INJECTION To test Fault handling, an EEC error can be generated. Both single and double-bit errors can be generated in both the read and write data paths. Read path Fault injection first reads the Flash data and then modifies it prior to entering the ECC logic. Write path Fault injection modifies the actual data prior to it being written into the target Flash and will cause an EEC error on a subsequent Flash read. The following procedure is used to inject a Fault: 1. 2. 3. 4. 5. 6. Load the Flash target address into the ECCADDR register. Select 1st Fault bit determined by FLT1PTRx (ECCCONH<7:0>). The target bit is inverted to create the Fault. If a double Fault is desired, select the 2nd Fault bit determined by FLT2PTRx (ECCCONH<15:8>), otherwise set to all `1's. Write the NVMKEY unlock sequence (see Section 5.5.3 "Program Flash Memory Control Registers"). Enable the ECC Fault injection logic by setting the FLTINJ bit (ECCCONL<0>). Perform a read or write to the Flash target address. Double-bit errors result in a generic hard trap. The ECCDBE bit (INTCON4<1>) will be set to identify the source of the hard trap. If no Interrupt Service Routine is implemented for the hard trap, a device Reset will also occur. The ECCSTATH register contains doublebit error status information. The DEDOUT bit is the expected calculated DED parity and DEDIN is the actual value from a Flash read operation. When no error is present, DEDIN equals DEDOUT. 2017-2018 Microchip Technology Inc. DS70005349C-page 79 dsPIC33CK256MP508 FAMILY 5.4 ICSPTM Write Inhibit ICSP Write Inhibit is an access restriction feature that, when activated, restricts all of Flash memory. Once activated, ICSP Write Inhibit permanently prevents ICSP Flash programming and erase operations, and cannot be deactivated. This feature is intended to prevent alteration of Flash memory contents, with behavior similar to One-Time-Programmable (OTP) devices. RTSP, including erase and programming operations, is not restricted when ICSP Write Inhibit is activated; however, code to perform these actions must be programmed into the device before ICSP Write Inhibit is activated. This allows for a bootloader-type application to alter Flash contents with ICSP Write Inhibit activated. Entry into ICSP and Enhanced ICSP modes is not affected by ICSP Write Inhibit. In these modes, it will continue to be possible to read configuration memory space and any user memory space regions which are not code protected. With ICSP writes inhibited, an attempt to set WR (NVMCON<15>) = 1 will maintain WR = 0, and instead, set WRERR (NVMCON<13>) = 1. All Enhanced ICSP erase and programming commands will have no effect with self-checked programming commands returning a FAIL response opcode (PASS if the destination already exactly matched the requested programming data). 5.4.1 ACTIVATING ICSPTM WRITE INHIBIT Caution: It is not possible to deactivate ICSP Write Inhibit. ICSP Write Inhibit is activated by executing a pair of NVMCON double-word programming commands to save two 16-bit activation values in the configuration memory space. The target NVM addresses and values required for activation are shown in Table 5-1. Once both addresses contain their activation values, ICSP Write Inhibit will take permanent effect on the next device Reset. Neither address can be reset, erased or otherwise modified, through any means, after being successfully programmed, even if one of the addresses has not been programmed. Only the lower 16 data bits stored at the activation addresses are evaluated; the upper 8 bits and second 24-bit word written by the double-word programming (NVMOP<3:0>) should be written as `0's. The addresses can be programmed in any order and also during separate ICSP/Enhanced ICSP/RTSP sessions, but any attempt to program an incorrect 16-bit value or use a row programming operation to program the values will be aborted without altering the existing data. TABLE 5-1: Once ICSP Write Inhibit is activated, it is not possible for a device executing in Debug mode to erase/write Flash, nor can a debug tool switch the device to Production mode. ICSP Write Inhibit should therefore only be activated on devices programmed for production. The JTAG port, when enabled, can be used to map ICSP signals to JTAG I/O pins. All Flash erase/ programming operations initiated via the JTAG port will therefore also be blocked after activating ICSP Write Inhibit.

The same programming algorithms are used for programming and erasing the Flash in the Inactive Partition, as described in Section 5.2 "RTSP Operation". On top of the page erase option, the entire Flash memory of the Inactive Partition can be erased by configuring the NVMOP<3:0> bits in the NVMCON register. Note 1: The application software to be loaded into the Inactive Partition will have the address of the Active Partition. The bootloader firmware will need to offset the address by 0x400000 in order to write to the Inactive Partition. 5.5.1 FLASH PARTITION SWAPPING The Boot Sequence Number is used for determining the Active Partition at start-up and is encoded within the FBTSEQ Configuration register bits. Unlike most Configuration registers, which only utilize the lower 16 bits of the program memory, FBTSEQ is a 24-bit Configuration Word. The Boot Sequence Number (BSEQ) is a 12-bit value and is stored in FBTSEQ twice. The true value is stored in bits, FBTSEQ<11:0>, and its complement is stored in bits, FBTSEQ<23:12>. At device Reset, the sequence numbers are read and the partition with the lowest sequence number becomes the Active Partition. If one of the Boot Sequence Numbers is invalid, the device will select the partition with the valid Boot Sequence Number, or default to Partition 1 if both sequence numbers are invalid. See Section 30.0 "Special Features" for more information. The BOOTSWP instruction provides an alternative means of swapping the Active and Inactive Partitions (soft swap) without the need for a device Reset. The BOOTSWP must always be followed by a GOTO instruction. The BOOTSWP instruction swaps the Active and Inactive Partitions, and the PC vectors to the location specified by the GOTO instruction in the newly Active Partition. For robustness of operation, in order to execute the BOOTSWP instruction, it is necessary to execute the NVM unlocking sequence as follows: 1. 2. 3. Write 0x55 to NVMKEY. Write 0xAA to NVMKEY. Execute the BOOTSWP instruction. If the unlocking sequence is not performed, the BOOTSWP instruction will be executed as a forced NOP and a GOTO instruction, following the BOOTSWP instruction, will be executed, causing the PC to jump to that location in the current operating partition. The SFTSWP and P2ACTIV bits in the NVMCON register are used to determine a successful swap of the Active and Inactive Partitions, as well as which partition is active. After the BOOTSWP and GOTO instructions, the SFTSWP bit should be polled to verify the partition swap has occurred and then cleared for the next panel swap event. 5.5.2 DUAL PARTITION MODES While operating in Dual Partition mode, the dsPIC33CK256MP508 family devices have the option for both partitions to have their own defined security segments, as shown in Figure 27-4. Alternatively, the device can operate in Protected Dual Partition mode, where Partition 1 becomes permanently erase/writeprotected. Protected Dual Partition mode allows for a "Factory Default" mode, which provides a fail-safe backup image to be stored in Partition 1. dsPIC33CK256MP508 family devices can also operate in Privileged Dual Partition mode, where additional security protections are implemented to allow for protection of intellectual property when multiple parties have software within the device. In Privileged Dual Partition mode, both partitions place additional restrictions on the FBSLIM register. These prevent changes to the size of the Boot Segment and General Segment, ensuring that neither segment will be altered. It is important to note that interrupts should temporarily be disabled while performing the soft swap sequence and that after the partition swap, all peripherals and interrupts which were enabled remain enabled. Additionally, the RAM and stack will maintain state after the switch. As a result, it is recommended that applications using soft swaps jump to a routine that will reinitialize the device in order to ensure the firmware runs as expected. The Configuration registers will have no effect during a soft swap. 2017-2018 Microchip Technology Inc.

The NVMCON register (Register 5-1) selects the operation to be performed (page erase, word/row program, Inactive Partition erase) and initiates the program or erase cycle. NVMKEY (Register 5-4) is a write-only register that is used for write protection. To start a programming or erase sequence, the user application must consecutively write 0x55 and 0xAA to the NVMKEY register. 2017-2018 Microchip Technology Inc. There are two NVM Address registers: NVMADRU and NVMADR. These two registers, when concatenated, form the 24-bit Effective Address (EA) of the selected word/row for programming operations, or the selected page for erase operations. The NVMADRU register is used to hold the upper eight bits of the EA, while the NVMADR register is used to hold the lower 16 bits of the EA. For row programming operation, data to be written to Program Flash Memory is written into data memory space (RAM) at an address defined by the NVMSRCADRL/H register (location of first element in row programming data).

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Reset" (DS70602) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. The Reset module combines all Reset sources and controls the device Master Reset Signal, SYSRST. The following is a list of device Reset sources: * * * * * * * * POR: Power-on Reset BOR: Brown-out Reset MCLR: Master Clear Pin Reset SWR: RESET Instruction WDTO: Watchdog Timer Time-out Reset CM: Configuration Mismatch Reset TRAPR: Trap Conflict Reset IOPUWR: Illegal Condition Device Reset - Illegal Opcode Reset - Uninitialized W Register Reset - Security Reset Note: Refer to the specific peripheral section or Section 4.0 "Memory Organization" of this data sheet for register Reset states. All types of device Reset set a corresponding status bit in the RCON register to indicate the type of Reset (see Register 6-1). A POR clears all the bits, except for the BOR and POR bits (RCON<1:0>) that are set. The user application can set or clear any bit, at any time, during code execution. The RCON bits only serve as status bits. Setting a particular Reset status bit in software does not cause a device Reset to occur. The RCON register also has other bits associated with the Watchdog Timer and device power-saving states. The function of these bits is discussed in other sections of this data sheet. Note: A simplified block diagram of the Reset module is shown in Figure 6-1. FIGURE 6-1: Any active source of Reset will make the SYSRST signal active. On system Reset, some of the registers associated with the CPU and peripherals are forced to a known Reset state, and some are unaffected. The status bits in the RCON register should be cleared after they are read so that the next RCON register value after a device Reset is meaningful. For all Resets, the default clock source is determined by the FNOSC<2:0> bits in the FOSCSEL Configuration register. The value of the FNOSCx bits is loaded into the NOSC<2:0> (OSCCON<10:8>) bits on Reset, which in turn, initializes the system clock.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Interrupts" (DS70000600) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. The dsPIC33CK256MP508 family interrupt controller reduces the numerous peripheral interrupt request signals to a single interrupt request signal to the dsPIC33CK256MP508 family CPU. 7.1.1 The Alternate Interrupt Vector Table (AIVT), shown in Figure 7-2, is available only when the Boot Segment (BS) is defined and the AIVT has been enabled. To enable the Alternate Interrupt Vector Table, the Configuration bit, AIVTDIS in the FSEC register, must be programmed and the AIVTEN bit must be set (INTCON2<8> = 1). When the AIVT is enabled, all interrupt and exception processes use the alternate vectors instead of the default vectors. The AIVT begins at the start of the last page of the Boot Segment, defined by BSLIM<12:0>. The second half of the page is no longer usable space. The Boot Segment must be at least two pages to enable the AIVT. Note: The interrupt controller has the following features: * Six Processor Exceptions and Software Traps * Seven User-Selectable Priority Levels * Interrupt Vector Table (IVT) with a Unique Vector for each Interrupt or Exception Source * Fixed Priority within a Specified User Priority Level * Fixed Interrupt Entry and Return Latencies * Alternate Interrupt Vector Table (AIVT) for Debug Support 7.1 Interrupt Vector Table The dsPIC33CK256MP508 family Interrupt Vector Table (IVT), shown in Figure 7-1, resides in program memory, starting at location, 000004h. The IVT contains six non-maskable trap vectors and up to 246 sources of interrupts. In general, each interrupt source has its own vector. Each interrupt vector contains a 24-bit wide address. The value programmed into each interrupt vector location is the starting address of the associated Interrupt Service Routine (ISR). Interrupt vectors are prioritized in terms of their natural priority. This priority is linked to their position in the vector table. Lower addresses generally have a higher natural priority. For example, the interrupt associated with Vector 0 takes priority over interrupts at any other vector address. 2017-2018 Microchip Technology Inc. ALTERNATE INTERRUPT VECTOR TABLE Although the Boot Segment must be enabled in order to enable the AIVT, application code does not need to be present inside of the Boot Segment. The AIVT (and IVT) will inherit the Boot Segment code protection. The AIVT supports debugging by providing a means to switch between an application and a support environment without requiring the interrupt vectors to be reprogrammed. This feature also enables switching between applications for evaluation of different software algorithms at run time. 7.2 Reset Sequence A device Reset is not a true exception because the interrupt controller is not involved in the Reset process. The dsPIC33CK256MP508 family devices clear their registers in response to a Reset, which forces the PC to zero. The device then begins program execution at location, 0x000000. A GOTO instruction at the Reset address can redirect program execution to the appropriate start-up routine.

This product page contains the latest updates and additional information. The IECx registers maintain all of the interrupt enable bits. These control bits are used to individually enable interrupts from the peripherals or external signals. 7.3.1 The IPCx registers are used to set the Interrupt Priority Level (IPL) for each source of interrupt. Each user interrupt source can be assigned to one of seven priority levels. KEY RESOURCES * "Interrupts" (DS70000600) in the "dsPIC33/ PIC24 Family Reference Manual" * Code Samples * Application Notes * Software Libraries * Webinars * All Related "dsPIC33/PIC24 Family Reference Manual" Sections * Development Tools 7.4 Interrupt Control and Status Registers The dsPIC33CK256MP508 family devices implement the following registers for the interrupt controller: * * * * * INTCON1 INTCON2 INTCON3 INTCON4 INTTREG 7.4.1 Global interrupt control functions are controlled from INTCON1, INTCON2, INTCON3 and INTCON4. INTCON1 contains the Interrupt Nesting Disable bit (NSTDIS), as well as the control and status flags for the processor trap sources. The INTCON2 register controls external interrupt request signal behavior, contains the Global Interrupt Enable bit (GIE) and the Alternate Interrupt Vector Table Enable bit (AIVTEN). INTCON3 contains the status flags for the Auxiliary PLL and DO stack overflow status trap sources. 7.4.2 Software IFSx The IFSx registers maintain all of the interrupt request flags. Each source of interrupt has a status bit, which is set by the respective peripherals or external signal and is cleared via software. 2017-2018 Microchip Technology Inc. 7.4.5 IPCx INTTREG The INTTREG register contains the associated interrupt vector number and the new CPU Interrupt Priority Level, which are latched into the Vector Number (VECNUM<7:0>) and Interrupt Level bits (ILR<3:0>) fields in the INTTREG register. The new Interrupt Priority Level is the priority of the pending interrupt. The interrupt sources are assigned to the IFSx, IECx and IPCx registers in the same sequence as they are listed in Table 7-1. For example, INT0 (External Interrupt 0) is shown as having Vector Number 8 and a natural order priority of 0. Thus, the INT0IF bit is found in IFS0<0>, the INT0IE bit in IEC0<0> and the INT0IP<2:0> bits in the first position of IPC0 (IPC0<2:0>). 7.4.6 INTCON1 THROUGH INTCON4 The INTCON4 register contains the Generated Hard Trap Status bit (SGHT). 7.4.4 STATUS/CONTROL REGISTERS Although these registers are not specifically part of the interrupt control hardware, two of the CPU Control registers contain bits that control interrupt functionality. For more information on these registers, refer to "dsPIC33E Enhanced CPU" (DS70005158) in the "dsPIC33/PIC24 Family Reference Manual". * The CPU STATUS Register, SR, contains the IPL<2:0> bits (SR<7:5>). These bits indicate the current CPU Interrupt Priority Level. The user software can change the current CPU Interrupt Priority Level by writing to the IPLx bits. * The CORCON register contains the IPL3 bit, which together with IPL<2:0>, also indicates the current CPU priority level. IPL3 is a read-only bit so that trap events cannot be masked by the user software. All Interrupt registers are described in Register 7-3 through Register 7-7 in the following pages.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "I/O Ports with Edge Detect" (DS70005322) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Many of the device pins are shared among the peripherals and the Parallel I/O ports. All I/O input ports feature Schmitt Trigger inputs for improved noise immunity. The PORT registers are located in the SFR. Some of the key features of the I/O ports are: 8.1 Parallel I/O (PIO) Ports All port pins have 12 registers directly associated with their operation as digital I/Os. The Data Direction register (TRISx) determines whether the pin is an input or an output. If the data direction bit is a `1', then the pin is an input. All port pins are defined as inputs after a Reset. Reads from the latch (LATx), read the latch. Writes to the latch, write the latch. Reads from the port (PORTx), read the port pins, while writes to the port pins, write the latch. Any bit and its associated data and control registers that are not valid for a particular device are disabled. This means the corresponding LATx and TRISx registers, and the port pin are read as zeros. When a pin is shared with another peripheral or function that is defined as an input only, it is nevertheless regarded as a dedicated port because there is no other competing source of outputs. Table 8-1 shows the pin availability. Table 8-2 shows the 5V input tolerant pins across this device. * Individual Output Pin Open-Drain Enable/Disable * Individual Input Pin Weak Pull-up and Pull-Down * Monitor Selective Inputs and Generate Interrupt when Change in Pin State is Detected * Operation during Sleep and Idle modes 2017-2018 Microchip Technology Inc.

DS70005349C-page 117 dsPIC33CK256MP508 FAMILY 8.1.1 OPEN-DRAIN CONFIGURATION In addition to the PORTx, LATx and TRISx registers for data control, port pins can also be individually configured for either digital or open-drain output. This is controlled by the Open-Drain Enable for PORTx register, ODCx, associated with each port. Setting any of the bits configures the corresponding pin to act as an open-drain output. The open-drain feature allows the generation of outputs, other than VDD, by using external pull-up resistors. The maximum open-drain voltage allowed on any pin is the same as the maximum VIH specification for that particular pin. 8.2 When the PORTx register is read, all pins configured as analog input channels are read as cleared (a low level). Pins configured as digital inputs do not convert an analog input. Analog levels on any pin, defined as a digital input (including the ANx pins), can cause the input buffer to consume current that exceeds the device specifications. 8.2.1 8.3 Configuring Analog and Digital Port Pins I/O PORT WRITE/READ TIMING One instruction cycle is required between a port direction change or port write operation and a read operation of the same port. Typically, this instruction would be a NOP. PORT Control Registers The following registers are in the PORT module: The ANSELx registers control the operation of the analog port pins. The port pins that are to function as analog inputs or outputs must have their corresponding ANSELx and TRISx bits set. In order to use port pins for I/O functionality with digital modules, such as timers, UARTs, etc., the corresponding ANSELx bit must be cleared. The ANSELx registers have a default value of 0xFFFF; therefore, all pins that share analog functions are analog (not digital) by default. Pins with analog functions affected by the ANSELx registers are listed with a buffer type of analog in the Pinout I/O Descriptions (see Table 1-1). * * * * * * * * * * * * Register 8-1: ANSELx (one per port) Register 8-2: TRISx (one per port) Register 8-3: PORTx (one per port) Register 8-4: LATx (one per port) Register 8-5: ODCx (one per port) Register 8-6: CNPUx (one per port) Register 8-7: CNPDx (one per port) Register 8-8: CNCONx (one per port - optional) Register 8-9: CNEN0x (one per port) Register 8-10: CNSTATx (one per port - optional) Register 8-11: CNEN1x (one per port) Register 8-12: CNFx (one per port) If the TRISx bit is cleared (output) while the ANSELx bit is set, the digital output level (VOH or VOL) is converted by an analog peripheral, such as the ADC module or comparator module.

This feature can detect input Change-of-States, even in Sleep mode, when the clocks are disabled. Every I/O port pin can be selected (enabled) for generating an interrupt request on a Change-of-State. Five control registers are associated with the Change Notification (CN) functionality of each I/O port. To enable the Change Notification feature for the port, the ON bit (CNCONx<15>) must be set. The CNEN0x and CNEN1x registers contain the CN interrupt enable control bits for each of the input pins. The setting of these bits enables a CN interrupt for the corresponding pins. Also, these bits, in combination with the CNSTYLE bit (CNCONx<11>), define a type of transition when the interrupt is generated. Possible CN event options are listed in Table 8-3. TABLE 8-3: CHANGE NOTIFICATION EVENT OPTIONS CNSTYLE Bit CNEN1x CNEN0x (CNCONx<11>) Bit Bit Change Notification Event Description 0 Does not matter 0 Disabled 0 Does not matter 1 Detects a mismatch between the last read state and the current state of the pin 1 0 0 Disabled 1 0 1 Detects a positive transition only (from `0' to `1') 1 1 0 Detects a negative transition only (from `1' to `0') 1 1 1 Detects both positive and negative transitions The CNSTATx register indicates whether a change occurred on the corresponding pin since the last read of the PORTx bit. In addition to the CNSTATx register, the CNFx register is implemented for each port. This register contains flags for Change Notification events. These flags are set if the valid transition edge, selected in the CNEN0x and CNEN1x registers, is detected. CNFx stores the occurrence of the event. CNFx bits must be cleared in software to get the next Change Notification interrupt. The CN interrupt is generated only for the I/Os configured as inputs (corresponding TRISx bits must be set). Note: Pull-ups and pull-downs on Input Change Notification pins should always be disabled when the port pin is configured as a digital output. 2017-2018 Microchip Technology Inc. 8.5 Peripheral Pin Select (PPS) A major challenge in general purpose devices is providing the largest possible set of peripheral features, while minimizing the conflict of features on I/O pins. The challenge is even greater on low pin count devices. In an application where more than one peripheral needs to be assigned to a single pin, inconvenient work arounds in application code, or a complete redesign, may be the only option. Peripheral Pin Select configuration provides an alternative to these choices by enabling peripheral set selection and placement on a wide range of I/O pins. By increasing the pinout options available on a particular device, users can better tailor the device to their entire application, rather than trimming the application to fit the device. The Peripheral Pin Select configuration feature operates over a fixed subset of digital I/O pins. Users may independently map the input and/or output of most digital peripherals to any one of these I/O pins. Hardware safeguards are included that prevent accidental or spurious changes to the peripheral mapping once it has been established. 8.5.1 AVAILABLE PINS The number of available pins is dependent on the particular device and its pin count. Pins that support the Peripheral Pin Select feature include the label, "RPn", in their full pin designation, where "n" is the remappable pin number. "RP" is used to designate pins that support both remappable input and output functions. 8.5.2 AVAILABLE PERIPHERALS The peripherals managed by the Peripheral Pin Select are all digital only peripherals. These include general serial communications (UART and SPI), general purpose timer clock inputs, timer-related peripherals (input capture and output compare) and interrupt-on-change inputs. In comparison, some digital only peripheral modules are never included in the Peripheral Pin Select feature. This is because the peripheral's function requires special I/O circuitry on a specific port and cannot be easily connected to multiple pins. One example includes I2C modules. A similar requirement excludes all modules with analog inputs, such as the A/D Converter (ADC) A key difference between remappable and nonremappable peripherals is that remappable peripherals are not associated with a default I/O pin. The peripheral must always be assigned to a specific I/O pin before it can be used. In contrast, non-remappable peripherals are always available on a default pin, assuming that the peripheral is active and not conflicting with another peripheral. DS70005349C-page 125 dsPIC33CK256MP508 FAMILY When a remappable peripheral is active on a given I/O pin, it takes priority over all other digital I/Os and digital communication peripherals associated with the pin. Priority is given regardless of the type of peripheral that is mapped. Remappable peripherals never take priority over any analog functions associated with the pin. 8.5.3 CONTROLLING PERIPHERAL PIN SELECT Peripheral Pin Select features are controlled through two sets of SFRs: one to map peripheral inputs and one to map outputs. Because they are separately controlled, a particular peripheral's input and output (if the peripheral has both) can be placed on any selectable function pin without constraint. The association of a peripheral to a peripheralselectable pin is handled in two different ways, depending on whether an input or output is being mapped. 8.5.4 INPUT MAPPING The inputs of the Peripheral Pin Select options are mapped on the basis of the peripheral. That is, a control register associated with a peripheral dictates the pin it will be mapped to. The RPINRx registers are used to configure peripheral input mapping. Each register contains sets of 8-bit fields, with each set associated with one of the remappable peripherals. Programming a given peripheral's bit field with an appropriate 8-bit index value maps the RPn pin with the corresponding value, or internal signal, to that peripheral. See Table 8-4 for a list of available inputs. FIGURE 8-2: REMAPPABLE INPUT FOR U1RX U1RXR<7:0> 0 VSS 1 CMP1 32 U1RX Input to Peripheral RP32 n RP181 Note: For input only, Peripheral Pin Select functionality does not have priority over TRISx settings. Therefore, when configuring an RPn pin for input, the corresponding bit in the TRISx register must also be configured for input (set to `1'). Physical connection to a pin can be made through RP32 through RP71. There are internal signals and virtual pins that can be connected to an input. Table 8-4 shows the details of the input assignment. For example, Figure 8-2 illustrates remappable pin selection for the U1RX input.

These six pins are internal to the devices and are not connected to a physical device pin. DS70005349C-page 128 These pins provide a simple way for inter-peripheral connection without utilizing a physical pin. For example, the output of the analog comparator can be connected to RP176 and the PWM Fault input can be configured for RP176 as well. This configuration allows the analog comparator to trigger PWM Faults without the use of an actual physical pin on the device. 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY TABLE 8-5: SELECTABLE INPUT SOURCES (MAPS INPUT TO FUNCTION) Input Name(1) Function Name Register Register Bits External Interrupt 1 INT1 RPINR0 INT1R<7:0> External Interrupt 2 INT2 RPINR1 INT2R<7:0> External Interrupt 3 INT3 RPINR1 INT3R<7:0> Timer1 External Clock T1CK RPINR2 T1CK<7:0> SCCP Timer1 TCKI1 RPINR3 TCKI1R<7:0> SCCP Capture 1 ICM1 RPINR3 ICM1R<7:0> SCCP Timer2 TCKI2 RPINR4 TCKI2R<7:0> SCCP Capture 2 ICM2 RPINR4 ICM2R<7:0> SCCP Timer3 TCKI3 RPINR5 TCKI3R<7:0> SCCP Capture 3 ICM3 RPINR5 ICM3R<7:0> SCCP Timer4 TCKI4 RPINR6 TCKI4R<7:0> SCCP Capture 4 ICM4 RPINR6 ICM4R<7:0> SCCP Timer5 TCKI5 RPINR7 TCKI5R<7:0> SCCP Capture 5 ICM5 RPINR7 ICM5R<7:0> SCCP Timer6 TCKI6 RPINR8 TCKI6R<7:0> SCCP Capture 6 ICM6 RPINR8 ICM6R<7:0> SCCP Timer7 TCKI7 RPINR9 TCKI7R<7:0> SCCP Capture 7 ICM7 RPINR9 ICM7R<7:0> SCCP Timer8 TCKI8 RPINR10 TCKI8R<7:0> SCCP Capture 8 ICM8 RPINR10 ICM8R<7:0> xCCP Fault A OCFA RPINR11 OCFAR<7:0> xCCP Fault B OCFB RPINR11 OCFBR<7:0> PWM PCI 8 PCI8 RPINR12 PCI8R<7:0> PWM PCI 9 PCI9 RPINR12 PCI9R<7:0> PWM PCI 10 PCI10 RPINR13 PCI10R<7:0> PWM PCI 11 PCI11 RPINR13 PCI11R<7:0> QEI1 Input A QEIA1 RPINR14 QEIA1R<7:0> QEI1 Input B QEIB1 RPINR14 QEIB1R<7:0> QEI1 Index 1 Input QEINDX1 RPINR15 QEINDX1R<7:0> QEI1 Home 1 Input QEIHOM1 RPINR15 QEIHOM1R<7:0> QEI2 Input A QEIA2 RPINR16 QEIA2R<7:0> QEI2 Input B QEIB2 RPINR16 QEIB2R<7:0> QEI2 Index 1 Input QEINDX2 RPINR17 QEINDX2R<7:0> QEI2 Home 1 Input QEIHOM2 RPINR17 QEIHOM2R<7:0> UART1 Receive UART1 Data-Set-Ready UART2 Receive U1RX RPINR18 U1RXR<7:0> U1DSR RPINR18 U1DSRR<7:0> U2RX RPINR19 U2RXR<7:0> U2DSRR<7:0> U2DSR RPINR19 SPI1 Data Input SDI1 RPINR20 SDI1R<7:0> SPI1 Clock Input SCK1IN RPINR20 SCK1R<7:0> SPI1 Slave Select SS1 RPINR21 SS1R<7:0> REFOI RPINR21 REFOIR<7:0> SDI2 RPINR22 SDI2R<7:0> UART2 Data-Set-Ready Reference Clock Input SPI2 Data Input Note 1: Unless otherwise noted, all inputs use the Schmitt Trigger input buffers. 2017-2018 Microchip Technology Inc.

DS70005349C-page 130 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 8.5.6 8.5.7 OUTPUT MAPPING In contrast to inputs, the outputs of the Peripheral Pin Select options are mapped on the basis of the pin. In this case, a control register associated with a particular pin dictates the peripheral output to be mapped. The RPORx registers are used to control output mapping. Each register contains sets of 6-bit fields, with each set associated with one RPn pin (see Register 8-54 through Register 8-80). The value of the bit field corresponds to one of the peripherals and that peripheral's output is mapped to the pin (see Table 8-7 and Figure 8-3). MAPPING LIMITATIONS The control schema of the peripheral select pins is not limited to a small range of fixed peripheral configurations. There are no mutual or hardware-enforced lockouts between any of the peripheral mapping SFRs. Literally, any combination of peripheral mappings, across any or all of the RPn pins, is possible. This includes both many-to-one and one-to-many mappings of peripheral inputs, and outputs to pins. While such mappings may be technically possible from a configuration point of view, they may not be supportable from an electrical point of view (see Table 8-6). A null output is associated with the output register Reset value of `0'. This is done to ensure that remappable outputs remain disconnected from all output pins by default.

DS70005349C-page 135 dsPIC33CK256MP508 FAMILY 8.5.8 1. 2. I/O HELPFUL TIPS In some cases, certain pins, as defined in Table 33-15 under "Injection Current", have internal protection diodes to VDD and VSS. The term, "Injection Current", is also referred to as "Clamp Current". On designated pins, with sufficient external current-limiting precautions by the user, I/O pin input voltages are allowed to be greater or lesser than the data sheet absolute maximum ratings, with respect to the VSS and VDD supplies. Note that when the user application forward biases either of the high or low-side internal input clamp diodes, that the resulting current being injected into the device that is clamped internally by the VDD and VSS power rails, may affect the ADC accuracy by four to six counts. I/O pins that are shared with any analog input pin (i.e., ANx) are always analog pins, by default, after any Reset. Consequently, configuring a pin as an analog input pin automatically disables the digital input pin buffer and any attempt to read the digital input level by reading PORTx or LATx will always return a `0', regardless of the digital logic level on the pin. To use a pin as a digital I/O pin on a shared ANx pin, the user application needs to configure the Analog Select for PORTx registers in the I/O ports module (i.e., ANSELx) by setting the appropriate bit that corresponds to that I/O port pin to a `0'. Note: Although it is not possible to use a digital input pin when its analog function is enabled, it is possible to use the digital I/O output function, TRISx = 0x0, while the analog function is also enabled. However, this is not recommended, particularly if the analog input is connected to an external analog voltage source, which would create signal contention between the analog signal and the output pin driver. DS70005349C-page 136 3. 4. 5. Most I/O pins have multiple functions. Referring to the device pin diagrams in this data sheet, the priorities of the functions allocated to any pins are indicated by reading the pin name, from left-to-right. The left most function name takes precedence over any function to its right in the naming convention. For example: AN16/T2CK/T7CK/RC1; this indicates that AN16 is the highest priority in this example and will supersede all other functions to its right in the list. Those other functions to its right, even if enabled, would not work as long as any other function to its left was enabled. This rule applies to all of the functions listed for a given pin. Each pin has an internal weak pull-up resistor and pull-down resistor that can be configured using the CNPUx and CNPDx registers, respectively. These resistors eliminate the need for external resistors in certain applications. The internal pull-up is up to ~(VDD - 0.8), not VDD. This value is still above the minimum VIH of CMOS and TTL devices. When driving LEDs directly, the I/O pin can source or sink more current than what is specified in the VOH/IOH and VOL/IOL DC characteristics specification. The respective IOH and IOL current rating only applies to maintaining the corresponding output at or above the VOH, and at or below the VOL levels. However, for LEDs, unlike digital inputs of an externally connected device, they are not governed by the same minimum VIH/VIL levels. An I/O pin output can safely sink or source any current less than that listed in the Absolute Maximum Ratings in Section 33.0 "Electrical Characteristics" of this data sheet. For example: VOH = 2.4v @ IOH = -8 mA and VDD = 3.3V The maximum output current sourced by any 8 mA I/O pin = 12 mA. LED source current < 12 mA is technically permitted. 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 6. The Peripheral Pin Select (PPS) pin mapping rules are as follows: a) Only one "output" function can be active on a given pin at any time, regardless if it is a dedicated or remappable function (one pin, one output). b) It is possible to assign a "remappable output" function to multiple pins and externally short or tie them together for increased current drive. c) If any "dedicated output" function is enabled on a pin, it will take precedence over any remappable "output" function. d) If any "dedicated digital" (input or output) function is enabled on a pin, any number of "input" remappable functions can be mapped to the same pin. e) If any "dedicated analog" function(s) are enabled on a given pin, "digital input(s)" of any kind will all be disabled, although a single "digital output", at the user's cautionary discretion, can be enabled and active as long as there is no signal contention with an external analog input signal. For example, it is possible for the ADC to convert the digital output logic level, or to toggle a digital output on a comparator or ADC input, provided there is no external analog input, such as for a built-in self-test. f) Any number of "input" remappable functions can be mapped to the same pin(s) at the same time, including to any pin with a single output from either a dedicated or remappable "output". g) The TRISx registers control only the digital I/O output buffer. Any other dedicated or remappable active "output" will automatically override the TRISx setting. The TRISx register does not control the digital logic "input" buffer. Remappable digital "inputs" do not automatically override TRISx settings, which means that the TRISx bit must be set to input for pins with only remappable input function(s) assigned. h) All analog pins are enabled by default after any Reset and the corresponding digital input buffer on the pin has been disabled. Only the Analog Select for PORTx (ANSELx) registers control the digital input buffer, not the TRISx register. The user must disable the analog function on a pin using the Analog Select for PORTx registers in order to use any "digital input(s)" on a corresponding pin, no exceptions. 2017-2018 Microchip Technology Inc. 8.5.9 I/O PORTS RESOURCES Many useful resources are provided on the main product page of the Microchip website for the devices listed in this data sheet.

Therefore, the user must start in either a nonPLL mode or clock switch to a non-PLL mode (e.g., internal FRC Oscillator) to make any necessary changes and then clock switch to the desired PLL mode. It is not permitted to directly clock switch from one PLL clock source to a different PLL clock source. The user would need to transition between PLL clock sources with a clock switch to a non-PLL clock source.

In this document, the instruction cycle clock is denoted by FCY. The timing diagram in Figure 9-5 illustrates the relationship between the system clock (FOSC), the instruction cycle clock (FCY) and the Program Counter (PC). The dsPIC33CK256MP508 devices can be configured to use any of the following clock configurations: * Primary Oscillator (POSC) on the OSCI and OSCO pins * Internal Fast RC Oscillator (FRC) with optional clock divider * Internal Low-Power RC Oscillator (LPRC) * Primary Oscillator with PLL (ECPLL, HSPLL, XTPLL) * Internal Fast RC Oscillator with PLL (FRCPLL) * Backup Internal Fast RC Oscillator (BFRC) FIGURE 9-5: The internal instruction cycle clock (FCY) can be output on the OSCO I/O pin if the Primary Oscillator mode (POSCMD<1:0>) is not configured as HS/XT.

This connection enables an external crystal (or ceramic resonator) to provide the clock to the device. The Primary Oscillator provides three modes of operation: The dsPIC33CK256MP508 family devices contain one instance of the Low-Power RC (LPRC) Oscillator and it provides a nominal clock frequency of 32 kHz, and is the clock source for the Power-up Timer (PWRT), Watchdog Timer (WDT) and Fail-Safe Clock Monitor (FSCM) circuits in the clock subsystem. * Medium Speed Oscillator (XT Mode): The XT mode is a Medium Gain, Medium Frequency mode used to work with crystal frequencies of 3.5 MHz to 10 MHz. * High-Speed Oscillator (HS Mode): The HS mode is a High-Gain, High-Frequency mode used to work with crystal frequencies of 10 MHz to 32 MHz. * External Clock Source Operation (EC Mode): If the on-chip oscillator is not used, the EC mode allows the internal oscillator to be bypassed. The device clocks are generated from an external source (0 MHz to up to 64 MHz) and input on the OSCI pin. The LPRC Oscillator is the clock source for the PWRT, WDT and FSCM. The LPRC Oscillator is enabled at power-on. 9.3 The LPRC Oscillator remains enabled under these conditions: * The FSCM is enabled * The WDT is enabled * The LPRC Oscillator is selected as the system clock If none of these conditions is true, the LPRC Oscillator shuts off after the PWRT expires. The LPRC Oscillator is shut off in Sleep mode. Internal Fast RC (FRC) Oscillator The dsPIC33CK256MP508 family devices contain one instance of the internal Fast RC (FRC) Oscillator and it provides a nominal 8 MHz clock without requiring an external crystal or ceramic resonator, which results in system cost savings for applications that do not require a precise clock reference. The application software can tune the frequency of the oscillator using the FRC Oscillator Tuning bits (TUN<5:0>) in the FRC Oscillator Tuning register (OSCTUN<5:0>).

It is not intended to be a comprehensive reference source. For more information, refer to "Direct Memory Access Controller (DMA)" (DS39742) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The Direct Memory Access (DMA) Controller is designed to service high data throughput peripherals operating on the SFR bus, allowing them to access data memory directly and alleviating the need for CPU-intensive management. By allowing these data-intensive peripherals to share their own data path, the main data bus is also deloaded, resulting in additional power savings. The DMA Controller functions both as a peripheral and a direct extension of the CPU. It is located on the microcontroller data bus, between the CPU and DMA-enabled peripherals, with direct access to SRAM. This partitions the SFR bus into two buses, allowing the DMA Controller access to the DMA-capable peripherals located on the new DMA SFR bus. The controller serves as a Master device on the DMA SFR bus, controlling data flow from DMA-capable peripherals. 2017-2018 Microchip Technology Inc. The controller also monitors CPU instruction processing directly, allowing it to be aware of when the CPU requires access to peripherals on the DMA bus and automatically relinquishing control to the CPU as needed. This increases the effective bandwidth for handling data without DMA operations, causing a processor Stall. This makes the controller essentially transparent to the user. The DMA Controller has these features: * Four Independently Programmable Channels * Concurrent Operation with the CPU (no DMA caused Wait states) * DMA Bus Arbitration * Five Programmable Address modes * Four Programmable Transfer modes * Four Flexible Internal Data Transfer modes * Byte or Word Support for Data Transfer * 16-Bit Source and Destination Address Register for each Channel, Dynamically Updated and Reloadable * 16-Bit Transaction Count Register, Dynamically Updated and Reloadable * Upper and Lower Address Limit Registers * Counter Half-Full Level Interrupt * Software Triggered Transfer * Null Write mode for Symmetric Buffer Operations A simplified block diagram of the DMA Controller is shown if Figure 10-1.

Each of these parameters can be independently configured for any transaction. In addition, any or all of the DMA channels can independently perform a different transaction at the same time. Transactions are classified by these parameters: * * * * Source and destination (SFRs and data RAM) Data size (byte or word) Trigger source Transfer mode (One-Shot, Repeated or Continuous) * Addressing modes (Fixed Address or Address Blocks with or without Address Increment/Decrement) In addition, the DMA Controller provides channel priority arbitration for all channels. 10.1.1 SOURCE AND DESTINATION Using the DMA Controller, data may be moved between any two addresses in the Data Space. The SFR space (0000h to 0FFFh) or the data RAM space (1000h to 4FFFh) can serve as either the source or the destination. Data can be moved between these areas in either direction or between addresses in either area. The four different combinations are shown in Figure 10-2. If it is necessary to protect areas of data RAM, the DMA Controller allows the user to set upper and lower address boundaries for operations in the Data Space above the SFR space. The boundaries are set by the DMAH and DMAL Limit registers. If a DMA channel attempts an operation outside of the address boundaries, the transaction is terminated and an interrupt is generated. 10.1.2 DATA SIZE The DMA Controller can handle both 8-bit and 16-bit transactions. Size is user-selectable using the SIZE bit (DMACHn<1>). By default, each channel is configured for word-size transactions. When byte-size transactions are chosen, the LSB of the source and/or destination address determines if the data represents the upper or lower byte of the data RAM location. 10.1.3 TRIGGER SOURCE The DMA Controller can use 82 of the device's interrupt sources to initiate a transaction. The DMA trigger sources occur in reverse order from their natural interrupt priority and are shown in Table 10-1. 2017-2018 Microchip Technology Inc. Since the source and destination addresses for any transaction can be programmed independently of the trigger source, the DMA Controller can use any trigger to perform an operation on any peripheral. This also allows DMA channels to be cascaded to perform more complex transfer operations. 10.1.4 TRANSFER MODE The DMA Controller supports four types of data transfers, based on the volume of data to be moved for each trigger. * One-Shot: A single transaction occurs for each trigger. * Continuous: A series of back-to-back transactions occur for each trigger; the number of transactions is determined by the DMACNTn transaction counter. * Repeated One-Shot: A single transaction is performed repeatedly, once per trigger, until the DMA channel is disabled. * Repeated Continuous: A series of transactions are performed repeatedly, one cycle per trigger, until the DMA channel is disabled. All transfer modes allow the option to have the source and destination addresses, and counter value, automatically reloaded after the completion of a transaction. 10.1.5 ADDRESSING MODES The DMA Controller also supports transfers between single addresses or address ranges. The four basic options are: * Fixed-to-Fixed: Between two constant addresses * Fixed-to-Block: From a constant source address to a range of destination addresses * Block-to-Fixed: From a range of source addresses to a single, constant destination address * Block-to-Block: From a range of source addresses to a range of destination addresses The option to select auto-increment or auto-decrement of source and/or destination addresses is available for Block Addressing modes. In addition to the four basic modes, the DMA Controller also supports Peripheral Indirect Addressing (PIA) mode, where the source or destination address is generated jointly by the DMA Controller and a PIA-capable peripheral. When enabled, the DMA channel provides a base source and/or destination address, while the peripheral provides a fixed range offset address.

When access collisions occur, the DMA Controller arbitrates between the channels using a user-selectable priority scheme. Two schemes are available: The channels of the DMA Controller can be individually powered down using the Peripheral Module Disable (PMD) registers. * Round Robin: When two or more channels collide, the lower numbered channel receives priority on the first collision. On subsequent collisions, the higher numbered channels each receive priority based on their channel number. * Fixed: When two or more channels collide, the lowest numbered channel always receives priority, regardless of past history; however, any channel being actively processed is not available for an immediate retrigger. If a higher priority channel is continually requesting service, it will be scheduled for service after the next lower priority channel with a pending request. The DMA Controller uses a number of registers to control its operation. The number of registers depends on the number of channels implemented for a particular device. 10.2 * DMACHn: DMA Channel n Control Register (Register 10-2) * DMAINTn: DMA Channel n Interrupt Register (Register 10-3) * DMASRCn: DMA Data Source Address Pointer for Channel n Register * DMADSTn: DMA Data Destination Source for Channel n Register * DMACNTn: DMA Transaction Counter for Channel n Register Typical Setup To set up a DMA channel for a basic data transfer: 1. Enable the DMA Controller (DMAEN = 1) and select an appropriate channel priority scheme by setting or clearing PRSSEL. 2. Program DMAH and DMAL with appropriate upper and lower address boundaries for data RAM operations. 3. Select the DMA channel to be used and disable its operation (CHEN = 0). 4. Program the appropriate source and destination addresses for the transaction into the channel's DMASRCn and DMADSTn registers. For PIA mode addressing, use the base address value. 5. Program the DMACNTn register for the number of triggers per transfer (One-Shot or Continuous modes) or the number of words (bytes) to be transferred (Repeated modes). 6. Set or clear the SIZE bit to select the data size. 7. Program the TRMODE<1:0> bits to select the Data Transfer mode. 8. Program the SAMODE<1:0> and DAMODE<1:0> bits to select the addressing mode. 9. Enable the DMA channel by setting CHEN. 10. Enable the trigger source interrupt. 2017-2018 Microchip Technology Inc. 10.4 Registers There are always four module-level registers (one control and three buffer/address): * DMACON: DMA Engine Control Register (Register 10-1) * DMAH and DMAL: DMA High and Low Address Limit Registers * DMABUF: DMA Transfer Data Buffer Each of the DMA channels implements five registers (two control and three buffer/address): For dsPIC33CK256MP508 devices, there are a total of 34 registers.

It is not intended to be a comprehensive reference source. For more information, refer to "CAN Flexible Data-Rate (FD) Protocol Module" (DS70005340) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). 2: Not all device variants include the CAN FD peripheral. Refer to Table 1 and Table 2 for availability. 11.1 Features The CAN FD module has the following features: General * Nominal (Arbitration) Bit Rate up to 1 Mbps * Data Bit Rate up to 8 Mbps * CAN FD Controller modes: - Mixed CAN 2.0B and CAN FD mode - CAN 2.0B mode * Conforms to ISO11898-1:2015 Message FIFOs * Seven FIFOs, Configurable as Transmit or Receive FIFOs * One Transmit Queue (TXQ) * Transmit Event FIFO (TEF) with 32-Bit Timestamp Message Transmission * Message Transmission Prioritization: - Based on priority bit field, and/or - Message with lowest ID gets transmitted first using the TXQ * Programmable Automatic Retransmission Attempts: Unlimited, Three Attempts or Disabled Message Reception * 16 Flexible Filter and Mask Objects. * Each Object can be Configured to Filter either: - Standard ID + first 18 data bits or - Extended ID * 32-Bit Timestamp. * The CAN FD Bit Stream Processor (BSP) Implements the Medium Access Control of the CAN FD Protocol Described in ISO11898-1:2015. It serializes and deserializes the bit stream, encodes and decodes the CAN FD frames, manages the medium access, Acknowledges frames, and detects and signals errors. * The TX Handler Prioritizes the Messages that are Requested for Transmission by the Transmit FIFOs. It uses the RAM interface to fetch the transmit data from RAM and provides it to the BSP for transmission. * The BSP provides Received Messages to the RX Handler. The RX handler uses acceptance filters to filter out messages that shall be stored in the Receive FIFOs. It uses the RAM interface to store received data into RAM. * Each FIFO can be Configured either as a Transmit or Receive FIFO. The FIFO control keeps track of the FIFO head and tail, and calculates the user address. In a TX FIFO, the user address points to the address in RAM where the data for the next transmit message shall be stored. In an RX FIFO, the user address points to the address in RAM where the data of the next receive message shall be read. The user notifies the FIFO that a message was written to or read from RAM by incrementing the head/tail of the FIFO. * The Transmit Queue (TXQ) is a Special Transmit FIFO that Transmits the Messages based on the ID of the Messages Stored in the Queue. * The Transmit Event FIFO (TEF) Stores the Message IDs of the Transmitted Messages. * A Free-Running Time Base Counter is used to Timestamp Received Messages. Messages in the TEF can also be timestamped. * The CAN FD Controller module Generates Interrupts when New Messages are Received or when Messages were Transmitted Successfully. Figure 11-1 shows the CAN FD system block diagram. 2017-2018 Microchip Technology Inc.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "12-Bit High-Speed, Multiple SARs A/D Converter (ADC)" (DS70005213) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices due to the number of implemented ADC channels. Refer to Table 1 and Table 2 for ADC channel availability on package variants. The dsPIC33CK256MP508 devices have a high-speed, 12-bit Analog-to-Digital Converter (ADC) that features a low conversion latency, high resolution and oversampling capabilities to improve performance in AC/DC, DC/DC power converters. The devices implement the ADC with three SAR cores, two dedicated and one shared. 13.1 ADC Features Overview The High-Speed, 12-Bit Multiple SARs Analog-to-Digital Converter (ADC) includes the following features: * Three ADC Cores: Two Dedicated Cores and One Shared (common) Core * User-Configurable Resolution of up to 12 Bits for each Core * Up to 3.5 Msps Conversion Rate per Channel at 12-Bit Resolution * Low-Latency Conversion * Up to 24 Analog Input Channels, with a Separate 16-Bit Conversion Result Register for each Input * Conversion Result can be Formatted as Unsigned or Signed Data, on a per Channel Basis, for All Channels 2017-2018 Microchip Technology Inc. * Simultaneous Sampling of up to Three Analog Inputs * Channel Scan Capability * Multiple Conversion Trigger Options for each Core, including: - PWM triggers from CPU cores - MCCP/SCCP modules triggers - CLC modules triggers - External pin trigger event (ADTRG31) - Software trigger * Four Integrated Digital Comparators with Dedicated Interrupts: - Multiple comparison options - Assignable to specific analog inputs * Four Oversampling Filters with Dedicated Interrupts: - Provide increased resolution - Assignable to a specific analog input The module consists of three independent SAR ADC cores. Simplified block diagrams of the Multiple SARs 12-Bit ADC are shown in Figure 13-1 and Figure 13-2. The analog inputs (channels) are connected through multiplexers and switches to the Sample-and-Hold (S&H) circuit of each ADC core. The core uses the channel information (the output format, the Measurement mode and the input number) to process the analog sample. When conversion is complete, the result is stored in the result buffer for the specific analog input, and passed to the digital filter and digital comparator if they were configured to use data from this particular channel. The ADC module can sample up to three inputs at a time (two inputs from the dedicated SAR cores and one from the shared SAR core). If multiple ADC inputs request conversion on the shared core, the module will convert them in a sequential manner, starting with the lowest order input. The ADC provides each analog input the ability to specify its own trigger source. This capability allows the ADC to sample and convert analog inputs that are associated with PWM generators operating on independent time bases.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "High-Speed Analog Comparator Module" (DS70005280) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The high-speed analog comparator module provides a method to monitor voltage, current and other critical signals in a power conversion application that may be too fast for the CPU and ADC to capture. There are a total of 3 comparator modules. The analog comparator module can be used to implement Peak Current mode control, Critical Conduction mode (variable frequency) and Hysteretic Control mode. 14.1 Overview The high-speed analog comparator module is comprised of a high-speed comparator, Pulse Density Modulation (PDM) DAC and a slope compensation unit. The slope compensation unit provides a user-defined slope which can be used to alter the DAC output. This feature is useful in applications, such as Peak Current mode control, where slope compensation is required to maintain the stability of the power supply. The user simply specifies the direction and rate of change for the slope compensation and the output of the DAC is modified accordingly. 2017-2018 Microchip Technology Inc. The DAC consists of a PDM unit, followed by a digitally controlled multiphase RC filter. The PDM unit uses a phase accumulator circuit to generate an output stream of pulses. The density of the pulse stream is proportional to the input data value, relative to the maximum value supported by the bit width of the accumulator. The output pulse density is representative of the desired output voltage. The pulse stream is filtered with an RC filter to yield an analog voltage. The output of the DAC is connected to the negative input of the comparator. The positive input of the comparator can be selected using a MUX from either of the input pins. The comparator provides a high-speed operation with a typical delay of 15 ns. The output of the comparator is processed by the pulse stretcher and the digital filter blocks, which prevent comparator response to unintended fast transients in the inputs. Figure 14-1 shows a block diagram of the high-speed analog comparator module. The DAC module can be operated in one of three modes: Slope Generation mode, Hysteretic mode and Triangle Wave mode. Each of these modes can be used in a variety of power supply applications. Note: The DACOUT1 pin can only be associated with a single DAC output at any given time. If more than one DACOEN bit is set, the DACOUT1 pin will be a combination of the signals.

Note 1: This data sheet summarizes the features of the dsPIC33CK256MP508 family of devices. It is not intended to be a comprehensive resource. For more information, refer to "Quadrature Encoder Interface (QEI)" (DS70000601) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The two channels, Phase A (QEAx) and Phase B (QEBx), are typically 90 degrees out of phase with respect to each other. The Phase A and Phase B channels have a unique relationship. If Phase A leads Phase B, the direction of the motor is deemed positive or forward. If Phase A lags Phase B, the direction of the motor is deemed negative or reverse. The Index pulse occurs once per mechanical revolution and is used as a reference to indicate an absolute position. Figure 15-1 illustrates the Quadrature Encoder Interface signals. The Quadrature Encoder Interface (QEI) module provides the interface to incremental encoders for obtaining mechanical position data. The dsPIC33CK256MP508 family implements two instances of the QEI. Quadrature Encoders, also known as incremental encoders or optical encoders, detect position and speed of rotating motion systems. Quadrature Encoders enable closed-loop control of motor control applications, such as Switched Reluctance (SR) and AC Induction Motors (ACIM). The Quadrature signals from the encoder can have four unique states (`01', `00', `10' and `11') that reflect the relationship between QEAx and QEBx. Figure 15-1 illustrates these states for one count cycle. The order of the states get reversed when the direction of travel changes. The Quadrature Decoder increments or decrements the 32-bit up/down Position x Counter (POSxCNTH/L) registers for each Change-of-State (COS). The counter increments when QEAx leads QEBx and decrements when QEBx leads QEAx. A typical Quadrature Encoder includes a slotted wheel attached to the shaft of the motor and an emitter/ detector module that senses the slots in the wheel. Typically, three output channels, Phase A (QEAx), FIGURE 15-1: QUADRATURE ENCODER INTERFACE SIGNALS QEAx QEBx POSxCNT +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 Up/Down 2017-2018 Microchip Technology Inc.

The QEI module consists of decoder logic to interpret the Phase A (QEAx) and Phase B (QEBx) signals, and an up/down counter to accumulate the count. The counter pulses are generated when the Quadrature state changes. The count direction information must be maintained in a register until a direction change is detected. The module also includes digital noise filters, which condition the input signal. DS70005349C-page 332 2017-2018 Microchip Technology Inc. 2017-2018 Microchip Technology Inc.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Multiprotocol Universal Asynchronous Receiver Transmitter (UART) Module" (DS70005288) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The Universal Asynchronous Receiver Transmitter (UART) is a flexible serial communication peripheral used to interface dsPIC(R) microcontrollers with other equipment, including computers and peripherals. The UART is a full-duplex, asynchronous communication channel that can be used to implement protocols, such as RS-232 and RS-485. The UART also supports the following hardware extensions: * * * * The primary features of the UART are: * Full or Half-Duplex Operation * Up to 8-Deep TX and RX First In, First Out (FIFO) Buffers * 8-Bit or 9-Bit Data Width * Configurable Stop Bit Length * Flow Control * Auto-Baud Calibration * Parity, Framing and Buffer Overrun Error Detection * Address Detect * Break Transmission * Transmit and Receive Polarity Control * Manchester Encoder/Decoder * Operation in Sleep mode * Wake from Sleep on Sync Break Received Interrupt LIN/J2602 IrDA(R) Direct Matrix Architecture (DMX) Smart Card 2017-2018 Microchip Technology Inc. DS70005349C-page 351 dsPIC33CK256MP508 FAMILY 16.1 Architectural Overview The UART transfers bytes of data, to and from device pins, using First-In First-Out (FIFO) buffers up to eight bytes deep. The status of the buffers and data is made available to user software through Special Function FIGURE 16-1: Registers (SFRs). The UART implements multiple interrupt channels for handling transmit, receive and error events. A simplified block diagram of the UART is shown in Figure 16-1.

The Idle state is high with a `Start' condition indicated by a falling edge. The Start bit is followed by the number of data, parity/address detect and Stop bits defined by the MOD<3:0> (UxMODE<3:0>) bits selected. FIGURE 16-2: UART CHARACTER FRAME Idle Idle Start Bit 16.3 D0 D1 D2 D3 Data Buffers Both transmit and receive functions use buffers to store data shifted to/from the pins. These buffers are FIFOs and are accessed by reading the SFRs, UxTXREG and UxRXREG, respectively. Each data buffer has multiple flags associated with its operation to allow software to read the status. Interrupts can also be configured based on the space available in the buffers. The transmit and receive buffers can be cleared and their pointers reset using the associated TX/RX Buffer Empty Status bits, UTXBE (UxSTAH<5>) and URXBE (UxSTAH<1>). 2017-2018 Microchip Technology Inc. D4 D5 D6 16.4 D7 Parity/ Address Stop Detect Bit(s) Protocol Extensions The UART provides hardware support for LIN/J2602, IrDA(R), DMX and smart card protocol extensions to reduce software overhead. A protocol extension is enabled by writing a value to the MOD<3:0> (UxMODE<3:0>) selection bits and further configured using the UARTx Timing Parameter registers, UxP1 (Register 16-9), UxP2 (Register 16-10), UxP3 (Register 16-11) and UxP3H (Register 16-12). Details regarding operation and usage are discussed in their respective chapters. Not all protocols are available on all devices. Please refer to the specific device data sheet for availability.

DS70005349C-page 371 dsPIC33CK256MP508 FAMILY NOTES: DS70005349C-page 372 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 17.0 SERIAL PERIPHERAL INTERFACE (SPI) Note 1: This data sheet summarizes the features of the dsPIC33CK256MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Serial Peripheral Interface (SPI) with Audio Codec Support" (DS70005136) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The Serial Peripheral Interface (SPI) module is a synchronous serial interface, useful for communicating with other peripheral or microcontroller devices. These peripheral devices may be serial EEPROMs, shift registers, display drivers, A/D Converters, etc. The SPI module is compatible with the Motorola(R) SPI and SIOP interfaces. All devices in the dsPIC33CK256MP508 family include three SPI modules. On 48, 64 and 80-pin devices, SPI instance SPI2 can work up to 50 MHz speed when selected as a non-PPS pin. The selection is done using the SPI2PIN bit (FDEVOPT<13>). If the bit for SPI2PIN is `1', the PPS pin will be used. When SPI2PIN is `0', the SPI signals are routed to dedicated pins. The module supports operation in two Buffer modes. In Standard mode, data is shifted through a single serial buffer. In Enhanced Buffer mode, data is shifted through a FIFO buffer. The FIFO level depends on the configured mode. Note: FIFO depth for this device is four (in 8-Bit Data mode). 2017-2018 Microchip Technology Inc. Variable length data can be transmitted and received, from 2 to 32 bits. Note: Do not perform Read-Modify-Write operations (such as bit-oriented instructions) on the SPIxBUF register in either Standard or Enhanced Buffer mode. The module also supports a basic framed SPI protocol while operating in either Master or Slave mode. A total of four framed SPI configurations are supported. The module also supports Audio modes. Four different Audio modes are available. * I2S mode * Left Justified mode * Right Justified mode * PCM/DSP mode In each of these modes, the serial clock is free-running and audio data is always transferred. If an audio protocol data transfer takes place between two devices, then usually one device is the Master and the other is the Slave. However, audio data can be transferred between two Slaves. Because the audio protocols require free-running clocks, the Master can be a third-party controller. In either case, the Master generates two free-running clocks: SCKx and LRC (Left, Right Channel Clock/SSx/FSYNC). The SPI serial interface consists of four pins: * SDIx: Serial Data Input * SDOx: Serial Data Output * SCKx: Shift Clock Input or Output * SSx: Active-Low Slave Select or Frame Synchronization I/O Pulse The SPI module can be configured to operate using two, three or four pins. In the 3-pin mode, SSx is not used. In the 2-pin mode, both SDOx and SSx are not used. DS70005349C-page 373 dsPIC33CK256MP508 FAMILY The SPI module has the ability to generate three interrupts reflecting the events that occur during the data communication. The following types of interrupts can be generated: 1. Receive interrupts are signalled by SPIxRXIF. This event occurs when: - RX watermark interrupt - SPIROV = 1 - SPIRBF = 1 - SPIRBE = 1 provided the respective mask bits are enabled in SPIxIMSKL/H. 2. Transmit interrupts are signalled by SPIxTXIF. This event occurs when: - TX watermark interrupt - SPITUR = 1 - SPITBF = 1 - SPITBE = 1 provided the respective mask bits are enabled in SPIxIMSKL/H. 3. General interrupts are signalled by SPIxGIF. This event occurs when: - FRMERR = 1 - SPIBUSY = 1 - SRMT = 1 provided the respective mask bits are enabled in SPIxIMSKL/H. Block diagrams of the module in Standard and Enhanced modes are shown in Figure 17-1 and Figure 17-2. Note: In this section, the SPI modules are referred to together as SPIx, or separately as SPI1, SPI2 or SPI3. Special Function Registers will follow a similar notation. For example, SPIxCON1 and SPIxCON2 refer to the control registers for any of the three SPI modules. DS70005349C-page 374 To set up the SPIx module for the Standard Master mode of operation: 1. 2. 3. 4. 5.

It is not intended to be a comprehensive reference source. For more information, refer to "Inter-Integrated Circuit (I2C)" (DS70000195) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The Inter-Integrated Circuit (I2C) module is a serial interface useful for communicating with other peripheral or microcontroller devices. These peripheral devices may be serial EEPROMs, display drivers, A/D Converters, etc. 18.1 The details of sending a message in Master mode depends on the communication protocol for the device being communicated with. Typically, the sequence of events is as follows: 1. 2. 3. 4. 5. 6. The I2C module supports these features: * Independent Master and Slave Logic * 7-Bit and 10-Bit Device Addresses * General Call Address as Defined in the I2C Protocol * Clock Stretching to Provide Delays for the Processor to Respond to a Slave Data Request * Both 100 kHz and 400 kHz Bus Specifications * Configurable Address Masking * Multi-Master modes to Prevent Loss of Messages in Arbitration * Bus Repeater mode, Allowing the Acceptance of All Messages as a Slave, regardless of the Address * Automatic SCL Communicating as a Master in a Single Master Environment 7. 8. 9. 10. 11. 12. 13. Assert a Start condition on SDAx and SCLx. Send the I 2C device address byte to the Slave with a write indication. Wait for and verify an Acknowledge from the Slave. Send the first data byte (sometimes known as the command) to the Slave. Wait for and verify an Acknowledge from the Slave. Send the serial memory address low byte to the Slave. Repeat Steps 4 and 5 until all data bytes are sent. Assert a Repeated Start condition on SDAx and SCLx. Send the device address byte to the Slave with a read indication. Wait for and verify an Acknowledge from the Slave. Enable Master reception to receive serial memory data. Generate an ACK or NACK condition at the end of a received byte of data. Generate a Stop condition on SDAx and SCLx. A block diagram of the module is shown in Figure 18-1. 2017-2018 Microchip Technology Inc.

EQUATION 18-1: COMPUTING BAUD RATE RELOAD VALUE(1,2,3,4) I2CxBRG = ((1/FSCL - Delay) * FCY/2) - 2 Note 1: Based on FCY = FOSC/2; Doze mode and PLL are disabled. 2: These clock rate values are for guidance only. The actual clock rate can be affected by various system-level parameters. The actual clock rate should be measured in its intended application. 3: Typical value of delay varies from 110 ns to 150 ns. 4: I2CxBRG values of 0 to 3 are expressly forbidden. The user should never program the I2CxBRG with a value of 0x0, 0x1, 0x2 or 0x3 as indeterminate results may occur. TABLE 18-1: Note 1: 2: Slave Address Masking The I2CxMSK register (Register 18-4) designates address bit positions as "don't care" for both 7-Bit and 10-Bit Addressing modes. Setting a particular bit location (= 1) in the I2CxMSK register causes the Slave module to respond, whether the corresponding address bit value is a `0' or a `1'. For example, when I2CxMSK is set to `0010000000', the Slave module will detect both addresses, `0000000000' and `0010000000'. To enable address masking, the Intelligent Peripheral Management Interface (IPMI) must be disabled by clearing the STRICT bit (I2CxCONL<11>). Note: As a result of changes in the I2C protocol, the addresses in Table 18-2 are reserved and will not be Acknowledged in Slave mode. This includes any address mask settings that include any of these addresses.

DS70005349C-page 414 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 20.0 SINGLE-EDGE NIBBLE TRANSMISSION (SENT) Note 1: This data sheet summarizes the features of this group of dsPIC33CK256MP508 family devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Single-Edge Nibble Transmission (SENT) Module" (DS70005145) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The Single-Edge Nibble Transmission (SENT) module is based on the SAE J2716, "SENT - Single-Edge Nibble Transmission for Automotive Applications". The SENT protocol is a one-way, single wire time modulated serial communication, based on successive falling edges. It is intended for use in applications where high-resolution sensor data needs to be communicated from a sensor to an Engine Control Unit (ECU). The SENTx module has the following major features: * * * * * * * * * Selectable Transmit or Receive mode Synchronous or Asynchronous Transmit modes Automatic Data Rate Synchronization Optional Automatic Detection of CRC Errors in Receive mode Optional Hardware Calculation of CRC in Transmit mode Support for Optional Pause Pulse Period Data Buffering for One Message Frame Selectable Data Length for Transmit/Receive from Three to Six Nibbles Automatic Detection of Framing Errors 2017-2018 Microchip Technology Inc. SENT protocol timing is based on a predetermined time unit, TTICK. Both the transmitter and receiver must be preconfigured for TTICK, which can vary from 3 to 90 s. A SENT message frame starts with a Sync pulse. The purpose of the Sync pulse is to allow the receiver to calculate the data rate of the message encoded by the transmitter. The SENT specification allows messages to be validated with up to a 20% variation in TTICK. This allows for the transmitter and receiver to run from different clocks that may be inaccurate, and drift with time and temperature. The data nibbles are 4 bits in length and are encoded as the data value + 12 ticks. This yields a 0 value of 12 ticks and the maximum value, 0xF, of 27 ticks. A SENT message consists of the following: * A synchronization/calibration period of 56 tick times * A status nibble of 12-27 tick times * Up to six data nibbles of 12-27 tick times * A CRC nibble of 12-27 tick times * An optional pause pulse period of 12-768 tick times Figure 20-1 shows a block diagram of the SENTx module. Figure 20-2 shows the construction of a typical 6-nibble data frame, with the numbers representing the minimum or maximum number of tick times for each section.

The module can be configured for continuous asynchronous message frame transmission, or alternatively, for Synchronous mode triggered by software. When enabled, the transmitter will send a Sync, followed by the appropriate number of data nibbles, an optional CRC and optional pause pulse. The tick period used by the SENTx transmitter is set by writing a value to the TICKTIME<15:0> (SENTxCON2<15:0>) bits. The tick period calculations are shown in Equation 20-1. EQUATION 20-1: TICK PERIOD CALCULATION TICKTIME<15:0> = TTICK -1 TCLK An optional pause pulse can be used in Asynchronous mode to provide a fixed message frame time period. The frame period used by the SENTx transmitter is set by writing a value to the FRAMETIME<15:0> (SENTxCON3<15:0>) bits. The formulas used to calculate the value of frame time are shown in Equation 20-2. EQUATION 20-2: FRAME TIME CALCULATIONS FRAMETIME<15:0> = TTICK/TFRAME FRAMETIME<15:0> 122 + 27N FRAMETIME<15:0> 848 + 12N 20.1.1.1 TRANSMIT MODE CONFIGURATION Initializing the SENTx Module Perform the following steps to initialize the module: 1. Write RCVEN (SENTxCON1<11>) = 0 for Transmit mode. 2. Write TXM (SENTxCON1<10>) = 0 for Asynchronous Transmit mode or TXM = 1 for Synchronous mode. 3. Write NIBCNT<2:0> (SENTxCON1<2:0>) for the desired data frame length. 4. Write CRCEN (SENTxCON1<8>) for hardware or software CRC calculation. 5. Write PPP (SENTxCON1<7>) for optional pause pulse. 6. If PPP = 1, write TFRAME to SENTxCON3. 7. Write SENTxCON2 with the appropriate value for the desired tick period. 8. Enable interrupts and set interrupt priority. 9. Write initial status and data values to SENTxDATH/L. 10. If CRCEN = 0, calculate CRC and write the value to CRC<3:0> (SENTxDATL<3:0>). 11. Set the SNTEN (SENTxCON1<15>) bit to enable the module. User software updates to SENTxDATH/L must be performed after the completion of the CRC and before the next message frame's status nibble. The recommended method is to use the message frame completion interrupt to trigger data writes. Where: TFRAME = Total time of the message from ms N = The number of data nibbles in message, 1-6 Note: The module will not produce a pause period with less than 12 ticks, regardless of the FRAMETIME<15:0> value. FRAMETIME<15:0> values beyond 2047 will have no effect on the length of a data frame. 2017-2018 Microchip Technology Inc. DS70005349C-page 417 dsPIC33CK256MP508 FAMILY 20.2 Receive Mode 20.2.1 The module can be configured for receive operation by setting the RCVEN (SENTxCON1<11>) bit. The time between each falling edge is compared to SYNCMIN<15:0> (SENTxCON3<15:0>) and SYNCMAX<15:0> (SENTxCON2<15:0>), and if the measured time lies between the minimum and maximum limits, the module begins to receive data. The validated Sync time is captured in the SENTxSYNC register and the tick time is calculated. Subsequent falling edges are verified to be within the valid data width and the data is stored in the SENTxDATL/H registers. An interrupt event is generated at the completion of the message and the user software should read the SENTx Data registers before the reception of the next nibble. The equation for SYNCMIN<15:0> and SYNCMAX<15:0> is shown in Equation 20-3. EQUATION 20-3: 20.2.1.1 Initializing the SENTx Module Perform the following steps to initialize the module: 1. 2. 3. 4. 5. 6. 7. 8. SYNCMIN<15:0> AND SYNCMAX<15:0> CALCULATIONS RECEIVE MODE CONFIGURATION Write RCVEN (SENTxCON1<11>) = 1 for Receive mode. Write NIBCNT<2:0> (SENTxCON1<2:0>) for the desired data frame length. Write CRCEN (SENTxCON1<8>) for hardware or software CRC validation. Write PPP (SENTxCON1<7>) = 1 if pause pulse is present. Write SENTxCON2 with the value of SYNCMAXx (Nominal Sync Period + 20%). Write SENTxCON3 with the value of SYNCMINx (Nominal Sync Period - 20%). Enable interrupts and set interrupt priority. Set the SNTEN (SENTxCON1<15>) bit to enable the module. The data should be read from the SENTxDATL/H registers after the completion of the CRC and before the next message frame's status nibble. The recommended method is to use the message frame completion interrupt trigger. TTICK = TCLK * (TICKTIME<15:0> + 1) FRAMETIME<15:0> = TTICK/TFRAME SyncCount = 8 x FRCV x TTICK SYNCMIN<15:0> = 0.8 x SyncCount SYNCMAX<15:0> = 1.2 x SyncCount FRAMETIME<15:0> 122 + 27N FRAMETIME<15:0> 848 + 12N Where: TFRAME = Total time of the message from ms N = The number of data nibbles in message, 1-6 FRCV = FCY x Prescaler TCLK = FCY/Prescaler For TTICK = 3.0 s SYNCMIN<15:0> = 76. Note: and FCLK = 4 MHz, To ensure a Sync period can be identified, the value written to SYNCMIN<15:0> must be less than the value written to SYNCMAX<15:0>.

The other modes are not available unless the module is reconfigured for the new mode. Note 1: This data sheet summarizes the features of the dsPIC33CK256MP508 family of devices. It is not intended to be a comprehensive reference source. For more information on the MCCP/SCCP modules, refer to "Capture/Compare/ PWM/Timer (MCCP and SCCP)" (DS33035) in the "dsPIC33/PIC24 Family Reference Manual". A conceptual block diagram for the module is shown in Figure 22-1. All three modes share a time base generator and a common Timer register pair (CCPxTMRH/L); other shared hardware components are added as a particular mode requires. dsPIC33CK256MP508 family devices include eight SCCP and one MCCP Capture/Compare/PWM/Timer base modules, which provide the functionality of three different peripherals from earlier PIC24F devices. The module can operate in one of three major modes: * General Purpose Timer * Input Capture * Output Compare/PWM The module is provided in two different forms, distinguished by the number of PWM outputs that the module can generate. Single Capture/Compare/PWM (SCCP) output modules provide only one PWM output. Multiple Capture/Compare/PWM (MCCP) output modules can provide up to six outputs and an extended range of power control features, depending on the pin count of the particular device. All other features of the modules are identical. FIGURE 22-1: Each module has a total of six control and status registers: * * * * * * CCPxCON1L (Register 22-1) CCPxCON1H (Register 22-2) CCPxCON2L (Register 22-3) CCPxCON2H (Register 22-4) CCPxCON3H (Register 22-6) CCPxSTATL (Register 22-7) Each module also includes eight buffer/counter registers that serve as Timer Value registers or data holding buffers: * CCPxTMRH/CCPxTMRL (CCPx Timer High/Low Counters) * CCPxPRH/CCPxPRL (CCPx Timer Period High/Low) * CCPxRA (CCPx Primary Output Compare Data Buffer) * CCPxRB (CCPx Secondary Output Compare Data Buffer) * CCPxBUFH/CCPxBUFL (CCPx Input Capture High/Low Buffers) SCCPx CONCEPTUAL BLOCK DIAGRAM CCPxIF External Capture Input Input Capture CCTxIF Sync/Trigger Out Special Trigger (to ADC) Clock Sources Time Base Generator CCPxTMRH/L Compare/PWM Output(s) T32 CCSEL MOD<3:0> Sync and Gating Sources 16/32-Bit Timer 2017-2018 Microchip Technology Inc. Output Compare/ PWM OCFA/OCFB DS70005349C-page 429 dsPIC33CK256MP508 FAMILY 22.1 Time Base Generator The Timer Clock Generator (TCG) generates a clock for the module's internal time base, using one of the clock signals already available on the microcontroller. This is used as the time reference for the module in its three major modes. The internal time base is shown in Figure 22-2. FIGURE 22-2: There are eight inputs available to the clock generator, which are selected using the CLKSEL<2:0> bits (CCPxCON1L<10:8>). Available sources include the FRC and LPRC, the Secondary Oscillator and the TCLKI External Clock inputs. The system clock is the default source (CLKSEL<2:0> = 000). TIMER CLOCK GENERATOR Clock Sources TMRPS<1:0> TMRSYNC SSDG Prescaler Clock Synchronizer Gate(1) To Rest of Module CLKSEL<2:0> Note 1: Gating is available in Timer modes only. 22.2 General Purpose Timer Timer mode is selected when CCSEL = 0 and MOD<3:0> = 0000. The timer can function as a 32-bit timer or a dual 16-bit timer, depending on the setting of the T32 bit (Table 22-1). TABLE 22-1: TIMER OPERATION MODE T32 (CCPxCON1L<5>) Operating Mode 0 Dual Timer Mode (16-bit) 1 Timer Mode (32-bit) Dual 16-Bit Timer mode provides a simple timer function with two independent 16-bit timer/counters. The primary timer uses CCPxTMRL and CCPxPRL. Only the primary timer can interact with other modules on the device. It generates the SCCPx sync out signals for use by other SCCP modules. It can also use the SYNC<4:0> bits signal generated by other modules. The secondary timer uses CCPxTMRH and CCPxPRH. It is intended to be used only as a periodic interrupt source for scheduling CPU events. It does not generate an output sync/trigger signal like the primary time base. In Dual Timer mode, the CCPx Secondary Timer Period register, CCPxPRH, generates the SCCP compare event (CCPxIF) used by many other modules on the device. The 32-Bit Timer mode uses the CCPxTMRL and CCPxTMRH registers, together, as a single 32-bit timer. When CCPxTMRL overflows, CCPxTMRH increments by one. This mode provides a simple timer function when it is important to track long time periods. Note that DS70005349C-page 430 the T32 bit (CCPxCON1L<5>) should be set before the CCPxTMRL or CCPxPRH registers are written to initialize the 32-bit timer. 22.2.1 SYNC AND TRIGGER OPERATION In both 16-bit and 32-bit modes, the timer can also function in either synchronization ("sync") or trigger operation. Both use the SYNC<4:0> bits (CCPxCON1H<4:0>) to determine the input signal source. The difference is how that signal affects the timer. In sync operation, the timer Reset or clear occurs when the input selected by SYNC<4:0> is asserted. The timer immediately begins to count again from zero unless it is held for some other reason. Sync operation is used whenever the TRIGEN bit (CCPxCON1H<7>) is cleared. SYNC<4:0> can have any value, except `11111'. In trigger operation, the timer is held in Reset until the input selected by SYNC<4:0> is asserted; when it occurs, the timer starts counting. Trigger operation is used whenever the TRIGEN bit is set. In Trigger mode, the timer will continue running after a trigger event as long as the CCPTRIG bit (CCPxSTATL<7>) is set. To clear CCPTRIG, the TRCLR bit (CCPxSTATL<5>) must be set to clear the trigger event, reset the timer and hold it at zero until another trigger event occurs. On dsPIC33CK256MP508 family devices, trigger operation can only be used when the system clock is the time base source (CLKSEL<2:0> = 000). 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 22.3 Output Compare Mode Output Compare mode compares the Timer register value with the value of one or two Compare registers, depending on its mode of operation. The Output Compare x module, on compare match events, has the ability to generate a single output transition or a train of TABLE 22-2: Table 22-2 shows the various modes available in Output Compare modes. OUTPUT COMPARE x/PWMx MODES MOD<3:0> T32 (CCPxCON1L<3:0>) (CCPxCON1L<5>) 22.4 output pulses. Like most PIC(R) MCU peripherals, the Output Compare x module can also generate interrupts on a compare match event.

The input capture features are useful in applications requiring frequency (time period) and pulse measurement. Single Edge Mode To use Input Capture mode, the CCSEL bit (CCPxCON1L<4>) must be set. The T32 and the MOD<3:0> bits are used to select the proper Capture mode, as shown in Table 22-3. Input Capture mode uses a dedicated 16/32-bit, synchronous, up counting timer for the capture function. The timer value is written to the FIFO when a capture event occurs. The internal value may be read (with a synchronization delay) using the CCPxTMRH/L register.

The auxiliary output is intended to connect to other SCCP modules, or other digital peripherals, to provide these types of functions: The type of output signal is selected using the AUXOUT<1:0> control bits (CCPxCON2H<4:3>).

It is not intended to be a comprehensive reference source. For more information, refer to "Configurable Logic Cell (CLC)" (DS70005298) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The information in this data sheet supersedes the information in the FRM. FIGURE 23-1: The Configurable Logic Cell (CLC) module allows the user to specify combinations of signals as inputs to a logic function and to use the logic output to control other peripherals or I/O pins. This provides greater flexibility and potential in embedded designs, since the CLC module can operate outside the limitations of software execution, and supports a vast amount of output designs. There are four input gates to the selected logic function. These four input gates select from a pool of up to 32 signals that are selected using four data source selection multiplexers. Figure 23-1 shows an overview of the module. Figure 23-3 shows the details of the data source multiplexers and Figure 23-2 shows the logic input gate connections.

DS70005349C-page 445 dsPIC33CK256MP508 FAMILY 23.1 Control Registers The CLCx Input MUX Select register (CLCxSEL) allows the user to select up to four data input sources using the four data input selection multiplexers. Each multiplexer has a list of eight data sources available. The CLCx module is controlled by the following registers: * * * * * CLCxCONL CLCxCONH CLCxSEL CLCxGLSL CLCxGLSH The CLCx Gate Logic Input Select registers (CLCxGLSL and CLCxGLSH) allow the user to select which outputs from each of the selection MUXes are used as inputs to the input gates of the logic cell. Each data source MUX outputs both a true and a negated version of its output. All of these eight signals are enabled, ORed together by the logic cell input gates. The CLCx Control registers (CLCxCONL and CLCxCONH) are used to enable the module and interrupts, control the output enable bit, select output polarity and select the logic function. The CLCx Control registers also allow the user to control the logic polarity of not only the cell output, but also some intermediate variables.

Refer to Table 1 and Table 2 for availability. The dsPIC33CK256MP508 family implements three instances of operational amplifiers (op amps). The op amps can be used for a wide variety of purposes, including signal conditioning and filtering. The three op amps are functionally identical. The block diagram for a single amplifier is shown in Figure 27-1. FIGURE 27-1: OAxIN- The op amps are controlled by two SFR registers: AMPCON1L and AMPCON1H. They remain in a lowpower state until the AMPON bit is set. Each op amp can then be enabled independently by setting the corresponding AMPENx bit (x = 1, 2, 3). The NCHDISx bit provides some flexibility regarding input range verses Integral Nonlinearity (INL). When NCHDISx = 0 (default), the op amps have a wider input voltage range (see Table 33-41 in Section 33.0 "Electrical Characteristics"). When NCHDISx = 1, the wider input range is traded for improved INL performance (lower INL). SINGLE OPERATIONAL AMPLIFIER BLOCK DIAGRAM - OAxOUT OAxIN+ + 2017-2018 Microchip Technology Inc.

To complement the information in this data sheet, refer to "Deadman Timer (DMT)" (DS70005155) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The primary function of the Deadman Timer (DMT) is to interrupt the processor in the event of a software malfunction. The DMT, which works on the system clock, is a free-running instruction fetch timer, which is clocked FIGURE 28-1: whenever an instruction fetch occurs, until a count match occurs. Instructions are not fetched when the processor is in Sleep mode. DMT can be enabled in the Configuration fuse or by software in the DMTCON register by setting the ON bit. The DMT consists of a 32-bit counter with a time-out count match value, as specified by the two 16-bit Configuration Fuse registers: FDMTCNTL and FDMTCNTH. A DMT is typically used in mission-critical and safetycritical applications, where any single failure of the software functionality and sequencing must be detected. Figure 28-1 shows a block diagram of the Deadman Timer module.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Watchdog Timer and Power-Saving Modes" (DS70615) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The dsPIC33CK256MP508 family devices provide the ability to manage power consumption by selectively managing clocking to the CPU and the peripherals. In general, a lower clock frequency and a reduction in the number of peripherals being clocked constitutes lower consumed power. dsPIC33CK256MP508 family devices can manage power consumption in four ways: * * * * Clock Frequency Instruction-Based Sleep and Idle modes Software-Controlled Doze mode Selective Peripheral Control in Software Combinations of these methods can be used to selectively tailor an application's power consumption while still maintaining critical application features, such as timing-sensitive communications. EXAMPLE 29-1: Sleep() Idle () Clock Frequency and Clock Switching The dsPIC33CK256MP508 family devices allow a wide range of clock frequencies to be selected under application control. If the system clock configuration is not locked, users can choose low-power or high-precision oscillators by simply changing the NOSCx bits (OSCCON<10:8>). The process of changing a system clock during operation, as well as limitations to the process, are discussed in more detail in Section 9.0 "Oscillator with High-Frequency PLL". 29.2 Instruction-Based Power-Saving Modes The dsPIC33CK256MP508 family devices have two special power-saving modes that are entered through the execution of a special PWRSAV instruction. Sleep mode stops clock operation and halts all code execution. Idle mode halts the CPU and code execution, but allows peripheral modules to continue operation. The assembler syntax of the PWRSAV instruction is shown in Example 29-1. Note: SLEEP_MODE and IDLE_MODE are constants defined in the assembler include file for the selected device. Sleep and Idle modes can be exited as a result of an enabled interrupt, WDT time-out or a device Reset. When the device exits these modes, it is said to "wake-up". PWRSAV INSTRUCTION SYNTAX IN ASSEMBLY PWRSAV #SLEEP_MODE PWRSAV #IDLE_MODE EXAMPLE 29-2: 29.1 ; Put the device into Sleep mode ; Put the device into Idle mode PWRSAV INSTRUCTION SYNTAX IN C LANGUAGE // Put the device into Sleep mode // Put the device into Idle mode 2017-2018 Microchip Technology Inc. DS70005349C-page 491 dsPIC33CK256MP508 FAMILY 29.2.1 SLEEP MODE 29.2.2 IDLE MODE The following occurs in Sleep mode: The following occurs in Idle mode: * The system clock source is shut down. If an on-chip oscillator is used, it is turned off. * The device current consumption is reduced to a minimum, provided that no I/O pin is sourcing current. * The Fail-Safe Clock Monitor does not operate, since the system clock source is disabled. * The LPRC clock continues to run in Sleep mode if the WDT is enabled. * The WDT, if enabled, is automatically cleared prior to entering Sleep mode. * Some device features or peripherals can continue to operate. This includes items such as the Input Change Notification on the I/O ports or peripherals that use an External Clock input. * Any peripheral that requires the system clock source for its operation is disabled. * The CPU stops executing instructions. * The WDT is automatically cleared. * The system clock source remains active. By default, all peripheral modules continue to operate normally from the system clock source, but can also be selectively disabled (see Section 29.4 "Peripheral Module Disable"). * If the WDT or FSCM is enabled, the LPRC also remains active. The device wakes up from Sleep mode on any of the these events: * Any interrupt source that is individually enabled * Any form of device Reset * A WDT time-out On wake-up from Sleep mode, the processor restarts with the same clock source that was active when Sleep mode was entered. For optimal power savings, the regulators can be configured to go into standby when Sleep mode is entered by clearing the VREGS (RCON<8>) bit (default configuration). If the application requires a faster wake-up time, and can accept higher current requirements, the VREGS (RCON<8>) bit can be set to keep the regulators active during Sleep mode. The available Low-Power Sleep modes are shown in Table 29-1. Additional regulator information is available in Section 30.4 "On-Chip Voltage Regulators". TABLE 29-1: Relative Power Highest * Any interrupt that is individually enabled * Any device Reset * A WDT time-out On wake-up from Idle mode, the clock is reapplied to the CPU and instruction execution will begin (2-4 clock cycles later), starting with the instruction following the PWRSAV instruction or the first instruction in the ISR. All peripherals also have the option to discontinue operation when Idle mode is entered to allow for increased power savings. This option is selectable in the control register of each peripheral; for example, the SIDL bit in the Timer1 Control register (T1CON<13>). 29.2.3 INTERRUPTS COINCIDENT WITH POWER SAVE INSTRUCTIONS Any interrupt that coincides with the execution of a PWRSAV instruction is held off until entry into Sleep or Idle mode has completed. The device then wakes up from Sleep or Idle mode. LOW-POWER SLEEP MODES LPWREN VREGS MODE Full power, active 0 1 -- 0 0 Full power, standby -- 1(1) 1 Low power, active Lowest 1(1) 0 Low power, standby Note 1: The device wakes from Idle mode on any of these events: Low-Power modes, when LPWREN = 1, can only be used in the industrial temperature range. DS70005349C-page 492 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 29.3 Doze Mode The preferred strategies for reducing power consumption are changing clock speed and invoking one of the power-saving modes. In some circumstances, this cannot be practical. For example, it may be necessary for an application to maintain uninterrupted synchronous communication, even while it is doing nothing else. Reducing system clock speed can introduce communication errors, while using a power-saving mode can stop communications completely. Doze mode is a simple and effective alternative method to reduce power consumption while the device is still executing code. In this mode, the system clock continues to operate from the same source and at the same speed. Peripheral modules continue to be clocked at the same speed, while the CPU clock speed is reduced. Synchronization between the two clock domains is maintained, allowing the peripherals to access the SFRs while the CPU executes code at a slower rate. Doze mode is enabled by setting the DOZEN bit (CLKDIV<11>). The ratio between peripheral and core clock speed is determined by the DOZE<2:0> bits (CLKDIV<14:12>). There are eight possible configurations, from 1:1 to 1:128, with 1:1 being the default setting. Programs can use Doze mode to selectively reduce power consumption in event-driven applications. This allows clock-sensitive functions, such as synchronous communications, to continue without interruption while the CPU Idles, waiting for something to invoke an interrupt routine. An automatic return to full-speed CPU operation on interrupts can be enabled by setting the ROI bit (CLKDIV<15>). By default, interrupt events have no effect on Doze mode operation. 29.4 A peripheral module is enabled only if both the associated bit in the PMD register is cleared and the peripheral is supported by the specific dsPIC(R) DSC variant. If the peripheral is present in the device, it is enabled in the PMD register by default. Note 1: If a PMD bit is set, the corresponding module is disabled after a delay of one instruction cycle. Similarly, if a PMD bit is cleared, the corresponding module is enabled after a delay of one instruction cycle (assuming the module control registers are already configured to enable module operation). 29.5 Power-Saving Resources Many useful resources are provided on the main product page of the Microchip website for the devices listed in this data sheet. This product page contains the latest updates and additional information. 29.5.1 KEY RESOURCES * "Watchdog Timer and Power-Saving Modes" (DS70615) in the "dsPIC33/PIC24 Family Reference Manual" * Code Samples * Application Notes * Software Libraries * Webinars * All related "dsPIC33/PIC24 Family Reference Manual" Sections * Development Tools Peripheral Module Disable The Peripheral Module Disable (PMD) registers provide a method to disable a peripheral module by stopping all clock sources supplied to that module. When a peripheral is disabled using the appropriate PMD control bit, the peripheral is in a minimum power consumption state. The control and status registers associated with the peripheral are also disabled, so writes to those registers do not have any effect and read values are invalid. 2017-2018 Microchip Technology Inc.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the related section of the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The dsPIC33CK256MP508 family devices include several features intended to maximize application flexibility and reliability, and minimize cost through elimination of external components. These are: * * * * * * * Flexible Configuration Watchdog Timer (WDT) Code Protection and CodeGuardTM Security JTAG Boundary Scan Interface In-Circuit Serial ProgrammingTM (ICSPTM) In-Circuit Emulation Brown-out Reset (BOR) 30.1 memory (from the Flash Configuration Words) each time the device is powered up. Configuration data is stored at the end of the on-chip program memory space, known as the Flash Configuration Words. Their specific locations are shown in Table 30-1. The configuration data is automatically loaded from the Flash Configuration Words to the proper Configuration Shadow registers during device Resets. The BSEQx bits (FBTSEQ<11:0>) determine which panel is the Active Partition at start-up and the Configuration Words from that panel are loaded into the Configuration Shadow registers. Note: Configuration data is reloaded on all types of device Resets. When creating applications for these devices, users should always specifically allocate the location of the Flash Configuration Words for configuration data in their code for the compiler. This is to make certain that program code is not stored in this address when the code is compiled. Program code executing out of configuration space will cause a device Reset. Note: Performing a page erase operation on the last page of program memory clears the Flash Configuration Words. Configuration Bits In dsPIC33CK256MP508 family devices, the Configuration Words are implemented as volatile memory. This means that configuration data will get loaded to volatile TABLE 30-1: dsPIC33CKXXXMPX0X CONFIGURATION ADDRESSES Register Name Single Partition 256k 128k Dual Partition, Active 256k 128k Dual Partition, Inactive 256k 128k FSEC(2) 0x02BF00 0x015F00 0x015F00 0x00AF00 0x415F00 0x40AF00 FBSLIM(2) 0x02BF10 0x015F10 0x015F10 0x00AF10 0x415F10 0x40AF10 (2) FSIGN 0x02BF14 0x015F14 0x015F14 0x00AF14 0x415F14 0x40AF14 FOSCSEL 0x02BF18 0x015F18 0x015F18 0x00AF18 0x415F18 0x40AF18 FOSC 0x02BF1C 0x015F1C 0x015F1C 0x00AF1C 0x415F1C 0x40AF1C FWDT 0x02BF20 0x015F20 0x015F20 0x00AF20 0x415F20 0x40AF20 FPOR 0x02BF24 0x015F24 0x015F24 0x00AF24 0x415F24 0x40AF24 FICD 0x02BF28 0x015F28 0x015F28 0x00AF28 0x415F28 0x40AF28 FDMTIVTL 0x02BF2C 0x015F2C 0x015F2C 0x00AF2C 0x415F2C 0x40AF2C FDMTIVTH 0x02BF30 0x015F30 0x015F30 0x00AF30 0x415F30 0x40AF30 FDMTCNTL 0x02BF34 0x015F34 0x015F34 0x00AF34 0x415F34 0x40AF34 FDMTCNTH 0x02BF38 0x015F38 0x015F38 0x00AF38 0x415F38 0x40AF38 FDMT 0x02BF3C 0x015F3C 0x015F3C 0x00AF3C 0x415F3C 0x40AF3C FDEVOPT 0x02BF40 0x015F40 0x015F40 0x00AF40 0x415F40 0x40AF40 FALTREG 0x02BF44 0x015F44 0x015F44 0x00AF44 0x415F44 0x40AF44 FBTSEQ 0x02BFFC 0x015FFC 0x015FFC 0x00AFFC 0x415FFC 0x40AFFC FBOOT(1) 0x801800 Note 1: FBOOT resides in calibration memory space. 2: Changes to the Inactive Partition Configuration Words affect how the Active Partition accesses the Inactive Partition. 2017-2018 Microchip Technology Inc.

The OTP Words can be used for storing checksums, code revisions, manufacturing dates, manufacturing lot numbers or any other application-specific information. A pair of voltage regulators, VREG1 and VREG2 together, provide power for the core. The PLL is powered using a separate regulator, VREGPLL, as shown in Figure 30-1. The regulators have Low-Power and Standby modes for use in Sleep modes. For additional information about Sleep, see Section 29.2.1 "Sleep Mode". On-Chip Voltage Regulators When the regulators are in Low-Power mode (LPWREN = 1), the power available to the core is limited. Before the LPWREN bit is set, the device should be placed into a lower power state by disabling peripherals and lowering CPU frequency (e.g., 8 MHz FRC without PLL). dsPIC33CK256MP508 family devices have a capacitorless internal voltage regulator to supply power to the core at 1.2V (typical). The output voltages of the three regulators can be controlled independently by the user, which gives the capability to save additional power during Sleep mode. The OTP area is not cleared by any erase command. This memory can be written only once. 30.4 FIGURE 30-1: INTERNAL REGULATOR VSS VREG1 VDD VREG2 CPU Core 0.1 F Ceramic PLL VREGPLL AVDD 0.1 F Ceramic DS70005349C-page 522 AVSS Band Gap Reference 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY REGISTER 30-20: VREGCON: VOLTAGE REGULATOR CONTROL REGISTER R/W-0 U-0 U-0 U-0 U-0 U-0 U-0 U-0 LPWREN(1) -- -- -- -- -- -- -- bit 15 bit 8 U-0 U-0 -- -- R/W-0 R/W-0 R/W-0 VREG3OV<1:0> R/W-0 R/W-0 VREG2OV<1:0> R/W-0 VREG1OV<1:0> bit 7 bit 0 Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as `0' -n = Value at POR `1' = Bit is set `0' = Bit is cleared bit 15 LPWREN: Low-Power Mode Enable bit(1) 1 = Voltage regulators are in Low-Power mode 0 = Voltage regulators are in Full Power mode bit 14-6 Unimplemented: Read as `1' bit 5-4 VREG3OV<1:0>: Low-Power Mode Enable bits 11/00 = VOUT = 1.5 * VBG = 1.2V 10 = VOUT = 1.25 * VBG = 1.0V 01 = VOUT = VBG = 0.8V bit 3-2 VREG2OV<1:0>: Low-Power Mode Enable bits 11/00 = VOUT = 1.5 * VBG = 1.2V 10 = VOUT = 1.25 * VBG = 1.0V 01 = VOUT = VBG = 0.8V bit 1-0 VREG1OV<1:0>: Low-Power Mode Enable bits 11/00 = VOUT = 1.5 * VBG = 1.2V 10 = VOUT = 1.25 * VBG = 1.0V 01 = VOUT = VBG = 0.8V Note 1: 30.5 x = Bit is unknown Low-Power mode can only be used within the industrial temperature range. The CPU should be run at slow speed (8 MHz or less) before setting this bit. Brown-out Reset (BOR) The Brown-out Reset (BOR) module is based on an internal voltage reference circuit that monitors the regulated supply voltage. The main purpose of the BOR module is to generate a device Reset when a brown-out condition occurs. Brown-out conditions are generally caused by glitches on the AC mains (for example, missing portions of the AC cycle waveform due to bad power transmission lines or voltage sags due to excessive current draw when a large inductive load is turned on). A BOR generates a Reset pulse which resets the device. The BOR selects the clock source based on the device Configuration bit selections. 2017-2018 Microchip Technology Inc. If an Oscillator mode is selected, the BOR activates the Oscillator Start-up Timer (OST). The system clock is held until OST expires. If the PLL is used, the clock is held until the LOCK bit (OSCCON<5>) is `1'. Concurrently, the PWRT Time-out (TPWRT) is applied before the internal Reset is released. If TPWRT = 0 and a crystal oscillator is being used, then a nominal delay of TFSCM is applied. The total delay in this case is TFSCM. Refer to Parameter SY35 in Table 33-25 of Section 33.0 "Electrical Characteristics" for specific TFSCM values. The BOR status bit (RCON<1>) is set to indicate that a BOR has occurred. The BOR circuit continues to operate while in Sleep or Idle mode and resets the device should VDD fall below the BOR threshold voltage. DS70005349C-page 523 dsPIC33CK256MP508 FAMILY 30.6 Dual Watchdog Timer (WDT) Note 1: This data sheet summarizes the features of the dsPIC33CK256MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Dual Watchdog Timer", (DS70005250) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip website (www.microchip.com). The dsPIC33 dual Watchdog Timer (WDT) is described in this section. Refer to Figure 30-2 for a block diagram of the WDT. FIGURE 30-2: The WDT, when enabled, operates from the internal Low-Power RC (LPRC) Oscillator clock source or a selectable clock source in Run mode. The WDT can be used to detect system software malfunctions by resetting the device if the WDT is not cleared periodically in software. The WDT can be configured in Windowed mode or Non-Windowed mode. Various WDT time-out periods can be selected using the WDT postscaler. The WDT can also be used to wake the device from Sleep or Idle mode (Power Save mode). If the WDT expires and issues a device Reset, the WTDO bit in RCON (Register 6-1) will be set. The following are some of the key features of the WDT modules: * Configuration or Software Controlled * Separate User-Configurable Time-out Periods for Run and Sleep/Idle * Can Wake the Device from Sleep or Idle * User-Selectable Clock Source in Run mode * Operates from LPRC in Sleep/Idle mode WATCHDOG TIMER BLOCK DIAGRAM Power Save Mode WDT LPRC Oscillator Power Save CLKSEL<1:0> SYSCLK Reserved FRC Oscillator LPRC Oscillator ON 32-Bit Counter Power Save Comparator Wake-up and NMI Reset SLPDIV<4:0> Run Mode WDT 00 01 Power Save 32-Bit Counter Comparator NMI and Start NMI Counter 10 11 Reset RUNDIV<4:0> WDTCLRKEY<15:0> = 5743h ON All Resets Clock Switch DS70005349C-page 524 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY REGISTER 30-21: WDTCONL: WATCHDOG TIMER CONTROL REGISTER LOW R/W-0 ON (1,2) U-0 U-0 R-y -- -- RUNDIV4(3) R-y R-y RUNDIV3(3) RUNDIV2(3) R-y R-y RUNDIV1(3) RUNDIV0(3) bit 15 bit 8 R R (3,5) CLKSEL1 R-y (3,5) CLKSEL0 SLPDIV4 R-y (3) R-y (3) SLPDIV3 SLPDIV2 R-y (3) SLPDIV1 R-y (3) HS/R/W-0 (3) SLPDIV0 WDTWINEN(4) bit 7 bit 0 Legend: HS = Hardware Settable bit y = Value from Configuration bit on POR R = Readable bit W = Writable bit U = Unimplemented bit, read as `0' -n = Value at POR `1' = Bit is set `0' = Bit is cleared x = Bit is unknown bit 15 ON: Watchdog Timer Enable bit(1,2) 1 = Enables the Watchdog Timer if it is not enabled by the device configuration 0 = Disables the Watchdog Timer if it was enabled in software bit 14-13 Unimplemented: Read as `0' bit 12-8 RUNDIV<4:0>: WDT Run Mode Postscaler Status bits(3) 11111 = Divide by 2 ^ 31 = 1,073,741,824 11110 = Divide by 2 ^ 30 = 526,870,912 ... 00001 = Divide by 2 ^ 2, 4 00000 = Divide by 2 ^ 1, 2 bit 7-6 CLKSEL<1:0>: WDT Run Mode Clock Select Status bits(3,5) 11 = LPRC Oscillator 10 = FRC Oscillator 01 = Reserved 00 = SYSCLK bit 5-1 SLPDIV<4:0>: Sleep and Idle Mode WDT Postscaler Status bits(3) 11111 = Divide by 2 ^ 31 = 1,073,741,824 11110 = Divide by 2 ^ 30 = 526,870,912 ... 00001 = Divide by 2 ^ 2, 4 00000 = Divide by 2 ^ 1, 2 bit 0 WDTWINEN: Watchdog Timer Window Enable bit(4) 1 = Enables Window mode 0 = Disables Window mode Note 1: 2: 3: 4: 5: A read of this bit will result in a `1' if the WDT is enabled by the device configuration or by software.

DS70005349C-page 526 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 30.7 JTAG Interface The dsPIC33CK256MP508 family devices implement a JTAG interface, which supports boundary scan device testing. Detailed information on this interface will be provided in future revisions of this document. Note: 30.8 Refer to "Programming and Diagnostics" (DS70608) in the "dsPIC33/PIC24 Family Reference Manual" for further information on usage, configuration and operation of the JTAG interface. In-Circuit Serial ProgrammingTM (ICSPTM) The dsPIC33CK256MP508 family devices can be serially programmed while in the end application circuit. This is done with two lines for clock and data, and three other lines for power, ground and the programming sequence. Serial programming allows customers to manufacture boards with unprogrammed devices and then program the device just before shipping the product. Serial programming also allows the most recent firmware or a custom firmware to be programmed. Refer to the "dsPIC33CK256MP508 Family Flash Programming Specification" (DS70005300) for details about In-Circuit Serial Programming (ICSP). Any of the three pairs of programming clock/data pins can be used: * PGC1 and PGD1 * PGC2 and PGD2 * PGC3 and PGD3 30.9 In-Circuit Debugger When MPLAB(R) ICD 3 or the REAL ICETM emulator is selected as a debugger, the in-circuit debugging functionality is enabled. This function allows simple debugging functions when used with MPLAB IDE. Debugging functionality is controlled through the PGCx (Emulation/Debug Clock) and PGDx (Emulation/Debug Data) pin functions. 30.10 Code Protection and CodeGuardTM Security dsPIC33CK256MP508 family devices offer multiple levels of security for protecting individual intellectual property. The program Flash protection can be broken up into three segments: Boot Segment (BS), General Segment (GS) and Configuration Segment (CS). Boot Segment has the highest security privilege and can be thought to have limited restrictions when accessing other segments. General Segment has the least security and is intended for the end user system code. Configuration Segment contains only the device user configuration data, which is located at the end of the program memory space. The code protection features are controlled by the Configuration registers, FSEC and FBSLIM. The FSEC register controls the code-protect level for each segment and if that segment is write-protected. The size of BS and GS will depend on the BSLIM<12:0> bits setting and if the Alternate Interrupt Vector Table (AIVT) is enabled. The BSLIM<12:0> bits define the number of pages for BS with each page containing 1024 IW. The smallest BS size is one page, which will consist of the Interrupt Vector Table (IVT) and 512 IW of code protection. If the AIVT is enabled, the last page of BS will contain the AIVT and will not contain any BS code. With AIVT enabled, the smallest BS size is now two pages (2048 IW), with one page for the IVT and BS code, and the other page for the AIVT. Write protection of the BS does not cover the AIVT. The last page of BS can always be programmed or erased by BS code. The General Segment will start at the next page and will consume the rest of program Flash, except for the Flash Configuration Words. The IVT will assume GS security only if BS is not enabled. The IVT is protected from being programmed or page erased when either security segment has enabled write protection. Any of the three pairs of debugging clock/data pins can be used: * PGC1 and PGD1 * PGC2 and PGD2 * PGC3 and PGD3 To use the in-circuit debugger function of the device, the design must implement ICSP connections to MCLR, VDD, VSS and the PGCx/PGDx pin pair. In addition, when the feature is enabled, some of the resources are not available for general use. These resources include the first 80 bytes of data RAM and two I/O pins (PGCx and PGDx). 2017-2018 Microchip Technology Inc. DS70005349C-page 527 dsPIC33CK256MP508 FAMILY The different device security segments are shown in Figure 30-3. Here, all three segments are shown, but are not required. If only basic code protection is required, then GS can be enabled independently or combined with CS, if desired. Privileged Dual Partition mode performs the same function as Protected Dual Partition mode, except additional constraints are applied in an effort to prevent code in the Boot Segment and General Segment from being used against each other. FIGURE 30-3: FIGURE 30-4: SECURITY SEGMENTS EXAMPLE 0x000000 IVT 0x000200 SECURITY SEGMENTS EXAMPLE (DUAL PARTITION MODES) 0x000000 IVT 0x000200 IVT and AIVT Assume BS Protection BS IVT Assumes BS Protection BS(2) AIVT + 512 IW(2) BSLIM<12:0> BSLIM<12:0> GS GS CS(1) 0x0XXX00 Note 1: 2: If CS is write-protected, the last page (GS + CS) of program memory will be protected from an erase condition. The last half (256 IW) of the last page of BS is unusable program memory. The dsPIC33CK256MP508 family can be operated in Dual Partition mode, where security is required for each partition. When operating in Dual Partition mode, the Active and Inactive Partitions both contain unique copies of the Reset vector and Interrupt Vector Tables (IVT, if enabled). Both partitions have the three security segments described previously. Code may not be executed from the Inactive Partition, but it may be programmed by, and read from, the Active Partition, subject to defined code protection. Figure 30-4 shows the different security segments for a device operating in Dual Partition mode. The device may also operate in a Protected Dual Partition mode or in Privileged Dual Partition mode. In Protected Dual Partition mode, Partition 1 is permanently erase/write-protected. This implementation allows for a "Factory Default" mode, which provides a fail-safe backup image to be stored in Partition 1. For example, a fail-safe bootloader can be placed in Partition 1, along with a fail-safe backup code image, which can be used or rewritten into Partition 2 in the event of a failed Flash update to Partition 2.

The last half (512 IW) of the last page of BS is unusable program memory. 2017-2018 Microchip Technology Inc. dsPIC33CK256MP508 FAMILY 31.0 Note: INSTRUCTION SET SUMMARY This data sheet summarizes the features of the dsPIC33CK256MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the "16-Bit MCU and DSC Programmer's Reference Manual" (DS70000157), which is available from the Microchip website (www.microchip.com). The dsPIC33CK256MP508 family instruction set is almost identical to that of the dsPIC30F and dsPIC33F. Most instructions are a single program memory word (24 bits). Only three instructions require two program memory locations. Each single-word instruction is a 24-bit word, divided into an 8-bit opcode, which specifies the instruction type and one or more operands, which further specify the operation of the instruction. The instruction set is highly orthogonal and is grouped into five basic categories: * * * * * Word or byte-oriented operations Bit-oriented operations Literal operations DSP operations Control operations Table 31-1 lists the general symbols used in describing the instructions. The dsPIC33 instruction set summary in Table 31-2 lists all the instructions, along with the status flags affected by each instruction. Most word or byte-oriented W register instructions (including barrel shift instructions) have three operands: * The first source operand, which is typically a register `Wb' without any address modifier * The second source operand, which is typically a register `Ws' with or without an address modifier * The destination of the result, which is typically a register `Wd' with or without an address modifier However, word or byte-oriented file register instructions have two operands: * The file register specified by the value `f' * The destination, which could be either the file register `f' or the W0 register, which is denoted as `WREG' 2017-2018 Microchip Technology Inc. Most bit-oriented instructions (including simple rotate/ shift instructions) have two operands: * The W register (with or without an address modifier) or file register (specified by the value of `Ws' or `f') * The bit in the W register or file register (specified by a literal value or indirectly by the contents of register `Wb') The literal instructions that involve data movement can use some of the following operands: * A literal value to be loaded into a W register or file register (specified by `k') * The W register or file register where the literal value is to be loaded (specified by `Wb' or `f') However, literal instructions that involve arithmetic or logical operations use some of the following operands: * The first source operand, which is a register `Wb' without any address modifier * The second source operand, which is a literal value * The destination of the result (only if not the same as the first source operand), which is typically a register `Wd' with or without an address modifier The MAC class of DSP instructions can use some of the following operands: * The accumulator (A or B) to be used (required operand) * The W registers to be used as the two operands * The X and Y address space prefetch operations * The X and Y address space prefetch destinations * The accumulator write-back destination The other DSP instructions do not involve any multiplication and can include: * The accumulator to be used (required) * The source or destination operand (designated as Wso or Wdo, respectively) with or without an address modifier * The amount of shift specified by a W register `Wn' or a literal value The control instructions can use some of the following operands: * A program memory address * The mode of the Table Read and Table Write instructions DS70005349C-page 529 dsPIC33CK256MP508 FAMILY Most instructions are a single word. Certain double-word instructions are designed to provide all the required information in these 48 bits. In the second word, the eight MSbs are `0's. If this second word is executed as an instruction (by itself), it executes as a NOP. The double-word instructions execute in two instruction cycles. Most single-word instructions are executed in a single instruction cycle, unless a conditional test is true or the Program Counter is changed as a result of the instruction, or a PSV or Table Read is performed. In these cases, the execution takes multiple instruction cycles, with the additional instruction cycle(s) executed as a NOP. Certain instructions that involve skipping over the subsequent instruction require either two or three TABLE 31-1: cycles if the skip is performed, depending on whether the instruction being skipped is a single-word or twoword instruction. Moreover, double-word moves require two cycles. Note: In dsPIC33CK256MP508 devices, read and Read-Modify-Write operations on non-CPU Special Function Registers require an additional cycle when compared to dsPIC30F, dsPIC33F, PIC24F and PIC24H devices. Note: For more details on the instruction set, refer to the "16-Bit MCU and DSC Programmer's Reference Manual" (DS70000157).

DS70005349C-page 539 dsPIC33CK256MP508 FAMILY 32.2 MPLAB XC Compilers The MPLAB XC Compilers are complete ANSI C compilers for all of Microchip's 8, 16 and 32-bit MCU and DSC devices. These compilers provide powerful integration capabilities, superior code optimization and ease of use. MPLAB XC Compilers run on Windows, Linux or MAC OS X. For easy source level debugging, the compilers provide debug information that is optimized to the MPLAB X IDE. The free MPLAB XC Compiler editions support all devices and commands, with no time or memory restrictions, and offer sufficient code optimization for most applications. MPLAB XC Compilers include an assembler, linker and utilities.

Note the following details of the code protection feature on Microchip devices: * Microchip products meet the specification contained in their particular Microchip Data Sheet. * Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. * There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. * Microchip is willing to work with the customer who is concerned about the integrity of their code. * Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable." Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
