All inputs are capable of reducing input threshold level
Time-multiplex means that the respective signals share the same pin on chip level and are active alternating in a dedicated
time slot (in modes where applicable).
Function-multiplex means that one of the respective signals sharing the same pin on chip level continuously uses the pin
depending on configuration and reset state.
