CR62, CR63 (Default 0x00)
These two registers select the GPIO6 base address [0x100:0xFFF] on 4byte boundary.
IO address:
CR70 (Default 0x00)
CRF0 (Default 0x00)
CRF1 (GP6 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.
CRF2 (GP6 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.
CRF3 (GP6 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.
CRF4 (GP6 output style register. Default 0x00 )
When set to a '1', the outgoing port is pulse mode.
When set to a '0', the outgoing port is level mode.
