AUTOCEN
Auto Convention Enable Bit
0 = Auto-convention Disabled.
1 = Auto-convention Enabled. When hardware receives TS in answer to reset state and the TS is
direct convention, CONSEL(SCnCR0[4]) will be set to 0 automatically, otherwise if the TS is
inverse convention, and CONSEL (SCnCR0[4]) will be set to 1.
Note:
If software enables auto convention function, the setting step must be done before Answer
to Reset state and the first data must be 0x3B or 0x3F. After hardware received first data and
stored it at buffer, hardware will decided the convention and change the CONSEL (SCnCR0[4])
bits automatically.

TXOFF
TX Transition Disable Bit
0 = The transceiver Enabled.
1 = The transceiver Disabled.
1
RXOFF
RX Transition Disable Bit
0 = The receiver Enabled.
1 = The receiver Disabled.
Note:
If AUTOCEN (SCnCR0[3])is enabled, these fields must be ignored.
0
SCEN
SC Engine Enable Bit
Set this bit to 1 to enable SC operation. If this bit is cleared, SC will force all transition to IDLE
state
Note:
SCEN must be set to 1 before filling in other registers, or ISO 7816-3 will not work properly.
