CRF1 (GP50-GP56 data register. Default 0x00 Bit 7: 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 (GP50-GP56 inversion register. Default 0x00 Bit 7: 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.
CRF3 (GP60-GP63 I/O selection register. Default 0xFF Bit 7-4: 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.
CRF4 (GP60-GP63 data register. Default 0xFF Bit 7-4: 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.
CRF5 (GP60-GP63 inversion register. Default 0x00 Bit 7-4: 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.
CRF6 (GP70-GP74 I/O selection register. Default 0xFF Bit 7-5: 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.
CRF7 (GP70-GP74 data register. Default 0xFF Bit 7-5: 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.
CRF8 (GP70-GP74 inversion register. Default 0x00 Bit 7-5: 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.
CRF9 (VID input data register. Bit 7 - 5: Reserved)
This register is read only. It contains original VID value.
Bit 7 – 5
: Reserved.
Bit 4 – 0
: Original VID value.
