CRDCKS1~CRDCKS0: Smart card interface clock source fCRD divided ratio selection
00: fCRD = fH /2
01: fCRD = fH /3
10: fCRD = fH /1
11: fCRD = fH /4
SMF: Smart card interface clock frequency fCCLK selection
0: fCCLK = fCRD
1: fCCLK = fCRD /2
SMCEN: Smart card interface clock enable control
0: fCCLK is disabled
1: fCCLK is enabled
This bit is used to control the Smart Card interface clock. If this bit is cleared to
disable the clock, the relevant registers in the Smart Card interface module can not be
accessed. When the Smart Card interface clock is disabled, it has no effect on the Card
insertion or removal detections.
Unimplemented, read as “0”
RETRY45: Card interface character transfer repetition times selection
0: 4 times
1: 5 times
RCIO: Card interface CIO pin pull high function enable control
0: Disable
1: Enable
RCDET: Card interface CDET pin pull high function enable control
0: Disable
1: Enable
