Chapter 5 External Bus Interface (S12XEBIV4)
1. All inputs are capable of reducing input threshold level
2. Time-multiplex means that the respective signals share the same pin on chip level and are active alternating in a dedicated
3. Function-multiplex means that one of the respective signals sharing the same pin on chip level continuously uses the pin
