0: GPIO6 is inactive.
0: GPIO5 is inactive.
0: WDTO# and PLED are inactive. 1: WDTO# and PLED are active.
These two registers select GPIO base address <100h: FF8h> on 4-byte
boundary.
GPIO5 I/O register
0: The respective GPIO5 PIN is programmed as an Output port
1: The respective GPIO5 PIN is programmed as an Input port.
GPIO5 Data register
For Output ports, the respective bits can be read and written by the pins.
For Input ports, the respective bits can be read only from pins. Write
accesses will be ignored.
GPIO5 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)
