W83627HF/ F/ HG/ G
CR70 （Default 0x09 if PNPCVS = 0 during POR, default 0x00 otherwise）
BIT
7 - 4
3 - 0
DESCRIPTION
Reserved.
These bits select IRQ resource for MIDI Port.
CRF0 （GP10-GP17 I/O 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 （GP10-GP17 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 （GP10-GP17 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.
CRF3 （Reserved）
This register is reserved.
