Debug and Test
AT91RM9200
All the I/O lines PA0 to PA31, PB0 to PB29, PC0 to PC31 and PD0 to PD27 integrate a program-
mable pull-up resistor of 15 kOhm typical. Programming of this pull-up resistor is performed
independently for each I/O line through the PIO Controllers.
After reset, all the I/O lines default as inputs with pull-up resistors enabled, except those which
are multiplexed with the External Bus Interface signals that must be enabled as peripherals at
reset. This is explicitly indicated in the column "Reset State" of the PIO Controller multiplexing
tables.
