3.2.6 Processor PIOs

This section describes all the signals connected to the SAMA7G5 MPU ports.

Some of the ports are multiplexed to accommodate more devices on the evaluation kit and to showcase all the functions the SAMA7G5 MPU can address off a single PIO wire. Most of the ports that share multiple functions are split through passive resistors placed on the board as close to the MPU as possible, therefore no other hardware change must be made. In most cases, the user can use only one of their functions at a time, or develop a composite driver enabling the use of multiple functions at the same time.
