CRF1 (GP3 data register. Default 0x00 when the port is active )
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 (GP3 inversion register. Default 0x00 when the port is active)
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 (GP4 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 (GP4 data register. Default 0x00 when the port is active)
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 (GP4 inversion register. Default 0x00 when the port is active)
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.
CRF6 (GP5 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.
CRF7 (GP5 data register. Default 0x00 when the port is active)
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.
CRF8 (GP5 inversion register. Default 0x00 when the port is active)
When set to a '1', the incoming/outgoing port value is inverted.
