14.2
Registers added with the Smart Card interface and bits for which the function changes are
described here.
14.2.1
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 standby mode.
Bits 7 to 4—Reserved: These bits are always read as 1 and cannot be modified.
Bit 3—Smart Card Data Transfer Direction (SDIR): Selects the serial/parallel conversion
format.
