General purpose input/output data
This register holds the value driven out to the pin if the pin is used as a general purpose output.
When not used with the alternative function (refer to
), these pins can be used as general purpose I/O.
If the associated data direction bits of these pins are set to 1, a read returns the value of the port register, otherwise
the buffered pin input state is read.

— Data input
A read always returns the buffered input state of the associated pin. It can be used to detect overload or short circuit
conditions on output pins.
