Peripheral Multiplexing on PIO Lines
The SAM7S Series features one PIO controller, PIOA, that multiplexes the I/O lines of the peripheral set.
PIO Controller A controls 32 lines (21 lines for SAM7S32/16). Each line can be assigned to one of two peripheral
functions, A or B. Some of them can also be multiplexed with the analog inputs of the ADC Controller.
“Multiplexing on PIO Controller A (SAM7S32/16),” on page 36 define how the I/O lines of the peripherals A, B or the
analog inputs are multiplexed on the PIO Controller A. 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.
All pins reset in their Parallel I/O lines function are 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.
