CR70 (Default 0x09 if PNPCSV = 0 during POR, default 0x00 otherwise)
Bit 7 - 4
: Reserved.
Bit [3:0]
: These bits select IRQ resource for MIDI Port .
CRF0 (GP5 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 (GP5 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 (GP5 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.
