Can be used as external DAC reset. Power down, active low. When power down is active, all output pins will be floated. The crystal oscillator will be stopped. To exit from power down mode, PDWN/ should be high and RESET/ applied. 6.9552 MHz (nominal) crystal connection (11.2896 MHz max) .

When used as general purpose I/O they can be individually configured as inputs or outputs. When used as alternate functions their meaning changes as follows : GPIO2 = DBCLK (input) GPIO3 = DBACK (output) GPIO4 = DBDATA (I/O) DBCLK, DBACK, DBDATA are used for debugging or external flash memory programming when DEBUG/ is low SAM9755 - Mobil Phone Synthesizer sam9755.pdf - Rev. 02/01 Dream S.A., an ATMEL company 4 (c) 2000-2001 Dream S.A.
