11.2 Peripheral Signal Multiplexing on I/O Lines
The SAM3X/A series product features 3 PIO (SAM3A and 100-pin SAM3X) or 4 PIO (144-pin
SAM3X) controllers, PIOA, PIOB, PIOC, PIOD, PIOE and PIOF, which multiplexes the I/O lines
of the peripheral set.
Each PIO Controller controls up to 32 lines. Each line can be assigned to one of two peripheral
functions, A or B. The multiplexing tables in the following paragraphs define how the I/O lines of
the peripherals A and B are multiplexed on the PIO Controllers. The column “Comments” has
been inserted in this table for the user’s own comments; it may be used to track how pins are
defined in an application.
Note that some peripheral function, which are output only, might be duplicated within both
tables.
