W83L518D
CR26 (Default 40h)
Bit 7: Reserved
Bit 6: HEFRAS, Extended Function Register Address Select. The corresponding power-on
setting pin is GP10 (PHEFRAS, pin 14). The HEFRAS is defaulted to "1" if PHEFRAS
is "0" and is defaulted to "0" if PHEFRAS is "1".
= 0 Extended Function Registers are at 2Eh/2Fh.
= 1 Extended Function Registers are at 4Eh/4Fh.
Bit 5: LOCKREG
= 0 Enable accesses of Configuration Registers.
= 1 Disable accesses of Configuration Registers.
Bit [4:0]: Reserved
CR29 (Default 00h, only valid in W83L518D)
Bit 7: Multi-function selection bit for pin 7 ~ 14
= 0 Pin 7 ~ 14 function as Smart Card interface socket B.
= 1 Pin 7 ~ 14 function as GPIO1.
Bit 6: Multi-function selection bit for pin 35 ~ 43
= 0 Pin 35 ~ 43 function as MSI/SDI socket B.
= 1 Pin 35 ~ 43 function as GPIO2.
Bit 5: Multi-function selection bit for pin 32 ~ 31 & pin 29 ~ 24.
= 0 Pin 32 ~ 31 and pin 29 ~ 24 function as MSA (MS interface card A).
= 1 Pin 32 ~ 31 and pin 29 ~ 24 function as SDA (SD interface card A).
Bit 4: Multi-function selection bit for pin 43 ~ 41 & pin 39 ~ 35.
= 0 Pin 43 ~ 41 & pin 39 ~ 35 function as MSB (MS interface card B).
= 1 Pin 43 ~ 41 & pin 39 ~ 35 function as SDB (MS interface card B).
Bit [3:0]: Reserved.
6.5 Logical Device 0 (Smart Card Interface)
CR30 (Default 0x00)
Bit [7:1]: Reserved.
Bit 0: Logical device active bit.
= 0 Logical device is inactive.
= 1 Activates the logical device.
CR60, CR61 (Default 0x00, 0x00)
These two registers select Smart Card base address [0x100:0xFFF] on 8-byte boundary.
CR70 (Default 0x00)
Bit [7:4]: Reserved.
Bit [3:0]: These bits select IRQ resource for Smart Card interface.
