the multiplexers to allow connection between the pin and the on chip peripherals.
Peripherals should be connected to the appropriate pins prior to being activated, and prior to any related interrupt(s) being
enabled. Activity of any enabled peripheral function that is not mapped to a related pin should be considered undefined.
