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 standby mode or module stop mode.
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.
Bit 2—Smart Card Data Invert (SINV): Specifies inversion of the data logic level. This function is used together with
the SDIR bit for communication with an inverse convention card. The SINV bit does not affect the logic level of the parity
bit. For parity-related setting procedures, see section 15.3.4, Register Settings.
Bit 1—Reserved: This bit cannot be modified and is always read as 1.
Bit 0—Smart Card Interface Mode Select (SMIF): Enables or disables the Smart Card interface function.
