Peripheral Signal Multiplexing on I/O Lines
The SAM4E device features five PIO Controllers on 144-pin versions (PIOA, PIOB, PIOC, PIOD and PIOE) that
multiplex the I/O lines of the peripheral set.
multiplex the I/O lines of the peripheral set.
The SAM4E 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 comments; it may be used to track how pins are defined in an application.
