CRF4 (GP20 ~ GP27 data register. Default 00h)
If a port is programmed to be an output port, its respective bit can be read/written and output to
respective pin. If a port is programmed to be an input port, its respective bit reflects what is on
respective pin.
CRF5 (GP20 ~ GP27 inversion register. Default 00h)
When set to "1", respective incoming/outgoing port value is inverted. When set to "0", respective
incoming/outgoing port value is the same as in data register.
6.8
CR30 (Default 0x00)
CR60, CR61 (Default 0x00, 0x00)
These two registers select SD Card interface base address [0x100:0xFFF] on 8-byte boundary.
CR70 (Default 0x00)
CR74 (Default 0x00)
CRF0 (Default 0x01)
