Input/Output Pin Function Selection (Port MUX)
24.2
The I/O port pins share peripheral module input/output pins. Each pin can be configured for use as an I/O port or
for a peripheral module function via the corresponding port function select bits. Pins not used for peripheral mod-
ules can be used as general-purpose I/O ports.
