Section 14 Smart Card Interface
14.2
This section describes the new or modified registers and bit functions in the smart card interface.
14.2.1
SCMR is an 8-bit readable/writable register that selects smart card interface functions.
Bit
Initial value
Read/Write
SCMR is initialized to H'F2 by a reset and in standby mode.
Bits 7 to 4—Reserved: Read-only bits, always read as 1.
Bit 3—Smart Card Data Transfer Direction (SDIR): Selects the serial/parallel conversion
format.
