CRF3 (GP5[5:0] I/O selection register. Default 0xFF)
When set to a '1', respective GPIO port is programmed as an input port.
When set to a '0', respective GPIO port is programmed as an output port.
CRF4 (GP5[5:0] data register. Default 0x00)
If a port is programmed to be an output port, then its respective bit can be read/written.
If a port is programmed to be an input port, then its respective bit can only be read.
CRF5 (GP5[5:0] inversion register. Default 0x00)
When set to a '1', the incoming/outgoing port value is inverted.
When set to a '0', the incoming/outgoing port value is the same as in data register.
7.1.7
CR30 (GP2[7:0] Default 0x00)
CRF0 (GP2[7:0] I/O selection register. Default 0xFF)

When set to a '0', respective GPIO port is programmed as an output port.
CRF1 (GP2[7:0] data register. Default 0x00)
If a port is programmed to be an output port, then its respective bit can be read/written.
If a port is programmed to be an input port, then its respective bit can only be read.
CRF2 (GP2[7:0] inversion register. Default 0x00)
When set to a '1', the incoming/outgoing port value is inverted.
When set to a '0', the incoming/outgoing port value is the same as in data register.
CRF3 (Default 0x00)
