The SAM4S features 2 PIO controllers on 48-pin, 64-pin versions (PIOA and PIOB) or 3 PIO
controllers on the 100-pin version (PIOA, PIOB and PIOC), that multiplex the I/O lines of the
peripheral set.
The SAM4S 64-pin and 100-pin PIO Controllers control up to 32 lines. Each line can be
assigned to one of three peripheral 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 com-
ments; 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.
