15.12 Logical Device B (Smart Card interface)
CR30 (Default 0x00)
CR60, CR 61 (Default 0x00, 0x00)
CR70 (Default 0x00)
15.13 Logical Device C (GPIO Port 5,6,7 This power of the Ports is Source VCC)
CR30 (Default 0x07)
CR60, CR 61 (Default 0x00)
CRF0 (GP50-GP56 I/O selection register. Default 0x00 Bit 7: 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.
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.
These two registers select Smart Card interface base address [0x100:0xFFF] on 8-byte boundary.
These two registers select the GP5, GP6, GP7 port base address [0x100:0xFFF] on 4 byte
boundary. GP5 is accessible through "base address", GP6 "base address" +1, and GP7 "base
address" +2.
Bit 7 - 1 : Reserved.
Bit 0
Bit 7 - 4 : Reserved.
Bit 3 - 0 : These bits select IRQ resource for Smart Card interface.
Bit 7 - 3 : Reserved.
