6.17 Logical Device F (GPIO Port 8)
CR30 (Default 0x00)
CR60, CR61 (Default 0x00)
These two registers select the GPIO8 base address [0x100:0xFFF] on 2byte boundary.
IO address :
CRF0 (GP8 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.
CRF1 (GP8 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 (GP8 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.
