The Smart Card supply voltage (C
It is controlled by several registers:
•
•
•
•
The register described in Section “SCICR Register” controls the CVCC voltage with
bits CVcc0, CVcc1
The register described in Section “SCCON Register”, switches ON/OFF the DC/DC
converter with bit CARDV
After the selection of the card voltage (CVcc[1:0]), the CARV
