7.10 Logical Device 7 (Game Port GPIO Port 1)
CR30 (Default 0x00)
CR60, CR 61 (Default 0x02, 0x01 if PNPCSV = 0 during POR, default 0x00 otherwise)
CR62, CR 63 (Default 0x00, 0x00)
CRF0 (GP10-GP17 I/O selection register. Default 0xFF)
CRF1 (GP10-GP17 data register. Default 0x00)
CRF2 (GP10-GP17 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.
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.
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.
These two registers select the GPIO1 base address [0x100:0xFFF] on 1 byte boundary
IO address : CRF1 base address
Bit 7 - 1: Reserved.
Bit 0: = 1 Activate Game Port./GP1
These two registers select the Game Port base address [0x100:0xFFF] on 8 byte boundary.
= 0 Game Port/GP1 is inactive.
