CR F4h. (GPIO4 I/O Register; Default FFh)
BIT READ / WRITE
DESCRIPTION
GPIO4 I/O register
7~0
R/W
0: The respective GPIO4 PIN is programmed as an output port
1: The respective GPIO4 PIN is programmed as an input port.
CR F5h. (GPIO4 Data Register; Default 00h)
BIT READ / WRITE
DESCRIPTION
R/W
GPIO4 Data register
7~0
For output ports, the respective bits can be read and written by the pins.
Read Only
For input ports, the respective bits can only be read by the pins. Write
accesses are ignored.
CR F6h. (GPIO4 Inversion Register; Default 00h)
BIT READ / WRITE
DESCRIPTION
GPIO4 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. (Applies to both input
and output ports)
