The AT91RM3400 features two PIO controllers (PIOA and PIOB) that allow multiplexing of the
I/O lines of the peripheral set.
Each PIO controller controls up to 32 lines. Each line can be assigned to one of the two
peripheral functions, A or B.
The tables in the following paragraphs define how the I/O lines of the peripheral A and B are
multiplexed on the PIO controllers A and B. The two columns “Function” and “Comments”
have been inserted for the user’s own comments; they may be used to track how pins are
defined in an application.
