Peripheral Signal Multiplexing on I/O Lines
The SAM3U features 3 PIO controllers, PIOA, PIOB and PIOC that multiplex 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 pages define how the I/O lines of
peripherals A and B are multiplexed on the PIO Controllers. The two columns “Extra Function”
and “Comments” have been inserted in this table for the user’s own comments, they 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.
