CRF7 (Default 0x00)
4.10 Logical Device 9 (GPIO Port 3 This power of the Port is standby source (VSB) )
CR30 (Default 0x00)
CRF0 (GP30-GP35 I/O selection register. Default 0xFF Bit 7-6: Reserve)
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.
CRF1 (GP30-GP35 data register. Default 0x00 Bit 7-6: Reserve)
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 (GP30-GP35 inversion register. Default 0x00 Bit 7-6: Reserve)
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.
