CR E5h. (GPIO2 Inversion register; Default 00h)
BIT READ / WRITE
DESCRIPTION
GPIO2 Inversion register
7~0
R/W
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)
CR F0h. (GPIO3 I/O register; Default FFh)
BIT READ / WRITE
DESCRIPTION
GPIO3 I/O register
7~0
R/W
0: The respective GPIO3 PIN is programmed as an Output port
1: The respective GPIO3 PIN is programmed as an Input port.
CR F1h. (GPIO3 Data register; Default 00h)
BIT READ / WRITE
DESCRIPTION
GPIO3 Data register
R/W
For Output ports, the respective bits can be read/written and produced to
7~0
pins.
Read Only
For Input ports, the respective bits can be read only from pins. Write
accesses will be ignored.
