SAM7X512/256/128 Summary
10.3
Peripheral Multiplexing on PIO Lines
The SAM7X512/256/128 features two PIO controllers, PIOA and PIOB, that multiplex the I/O
lines of the peripheral set.
Each PIO Controller controls 31 lines. Each line can be assigned to one of two peripheral func-
tions, A or B. Some of them can also be multiplexed with the analog inputs of the ADC
Controller.
Table 10-2 on page 32 and Table 10-3 on page 33 defines how the I/O lines of the peripherals A,
B or the analog inputs are multiplexed on the PIO Controller A and PIO Controller B. The two
columns “Function” and “Comments” have been inserted for the user’s own comments; they may
be used to track how pins are defined in an application.
Note that some peripheral functions that are output only, may be duplicated in the table.
At reset, all I/O lines are automatically configured as input with the programmable pull-up
enabled, so that the device is maintained in a static state as soon as a reset is detected.
