The SAM3N product features 2 PIO controllers (48-pin and 64-pin version) or 3 PIO controllers
(100-pin version), PIOA, PIOB and PIOC, that multiplex the I/O lines of the peripheral set.
The SAM3N 64-pin and 100-pin PIO Controller controls up to 32 lines (see
able according to pin count,” on page
functions: A, B or C. The multiplexing tables in the following paragraphs define how the I/O lines
of the peripherals A, B and C 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 functions which are output only, might be duplicated within the tables.
