The following table summarizes the effect of the various configuration bits, that is data direction (DDR),
output level (PORT/PT), pull enable (PER), pull select (PPS), interrupt enable (PIE) on the pin function,
pull device and interrupt activity.
The configuration bit PPS is used for two purposes:
