12.10 Logical Device 8 ( GPIO Port 2)
CR30 (Default 0x00)
CR62, CR 63 (Default 0x00, 0x00)
CRF0 (GP10-GP17 I/O selection register. Default 0xFF)
CRF1 (GP10-GP17 data register. Default 0x00 when the port is active)
CRF2 (GP10-GP17 inversion register. Default 0x00 when the port is active)
12.11 Logical Device 9 (GPIO Port 3 ~ GPIO Port 5 )
CR30 (Default 0x00)
CR60,61(Default 0x00,0x00).
CRF0 (GP3 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.
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.
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.
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
Bit 7 ~ 3: Reserved.
Bit 2: = 1 Activate GPIO5.
Bit 1: = 1 Activate GPIO4.
Bit 0: = 1 Activate GPIO3.
These two registers select the GPIO1 base address [0x100:0xFFF] on 1 byte boundary
IO address : CRF1 base address
These two registers select the GP 3,4,5 base address(0x100:FFE) ON 3 bytes boundary.
