Revision 1.3
CR62, CR 63 (Default 0x03, 0x30 if PNPCSV = 0 during POR, default 0x00 otherwise)
These two registers select the MIDI Port base address [0x100:0xFFF] on 2 byte boundary.
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 (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.
8.3.8 Logical Device 8 (GPIO Port 2 This power of the Port is VCC source)
CR30 (GP20-GP27 Default 0x00)
Bit 7 - 1 : Reserved.
Bit 0
= 1 Activate GPIO2.
= 0 GPIO2 is inactive.
CRF0 (GP20-GP27 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 (GP20-GP27 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 (GP20-GP27 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.
