15.2
Registers added with the smart card interface and bits for which the function changes are
described here.
15.2.1
SCMR is an 8-bit readable/writable register that selects the smart card interface function.
SCMR is initialized to H'F2 by a reset and in hardware standby mode. In software standby mode
and module stop mode it retains its previous state.
Bits 7 to 4—Reserved: These bits cannot be modified and are always read as 1.
Bit 3—Smart Card Data Transfer Direction (SDIR): Selects the serial/parallel conversion
format.
