8.3 Peripheral Signal Multiplexing on I/O Lines
The SAMA5D4 product features five PIO controllers: PIOA, PIOB, PIOC, PIOD, and PIOE, that multiplex the I/O
lines of the peripheral set.
Each line can be assigned to one of three peripheral functions: A, B, or C. The multiplexing tables in the pin
description paragraphs define how the I/O lines of the peripherals A, B and C are multiplexed on the PIO
Controllers.
Note that some peripheral functions which are output only, might be duplicated within the both tables.
The column “Reset State” indicates whether the PIO Line resets in I/O mode or in peripheral mode. If I/O is
mentioned, the PIO line resets in input with the pull-up enabled, so that the device is maintained in a static state as
soon as the reset is released. As a result, the bit corresponding to the PIO line in PIO_PSR (Peripheral Status
Register) resets low.
If a signal name is mentioned in the “Reset State” column, the PIO line is assigned to this function and the
corresponding bit in PIO_PSR resets high. This is the case of pins controlling memories, in particular the address
lines, which require the pin to be driven as soon as the reset is released. Note that the pull-up resistor is also
enabled in this case.
