PIO Configuration
Peripheral Signals Multiplexing on I/O Lines
The AT91SAMM10 product features 5 PIO controllers, PIOA, PIOB, PIOC, PIOD and PIOE, which multi-
plex 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 paragraphs
define how the I/O lines of peripherals A and B are multiplexed on the PIO Controllers.
