GPIO4 I/O register
0: The respective GPIO4 PIN is programmed as an Output port
1: The respective GPIO4 PIN is programmed as an Input port.
GPIO4 Data register
For Output ports, the respective bits can be read/written and produced to
pins.
For Input ports, the respective bits can be read only from pins. Write
accesses will be ignored.
GPIO4 Inversion register
0: The respective bit and the port value are the same.
1: The respective bit and the port value are inverted. (Both Input & Output
ports)
