CRF7 (Default 0x00)
15.10 Logical Device 9 (GPIO Port 3,4 are powered by standby source VSB)
CR30 (Default 0x02)
CR60, CR 61 (Default 0x02, 0x90 if PNPCSV = 0 during POR, default 0x00 otherwise)
CRF0 (GP30-GP35 I/O selection register. Default 0xFF Bit 7 - 6: Reserved)
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: Reserved)
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: Reserved)
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.
These two registers select the GP3, GP4 port base address [0x100:0xFFF] on 2 byte boundary.
GP3 is accessible through "base address" and GP4 is accessible through "base address" +1.
