Section 12 Serial Communication Interface (SCI)
12.2.9
SCMR selects LSB-first or MSB-first by means of bit SDIR. Except in the case of asynchronous
mode 7-bit data, LSB-first or MSB-first can be selected regardless of the serial communication
mode. The descriptions in this chapter refer to LSB-first transfer.
For details of the other bits in SCMR, see section 13.2.1, Smart Card Mode Register (SCMR).
SCMR is initialized to H'F2 by a reset, and in standby mode or module stop 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.
The transmit/receive format is valid for 8-bit data.

Bit 2—Smart Card Data Invert (SINV): When the smart card interface operates as a normal
SCI, 0 should be written in this bit.
Bit 1—Reserved: Read-only bit, always read as 1.
Bit 0—Smart Card Interface Mode Select (SMIF): When the smart card interface operates as a
normal SCI, 0 should be written in this bit.
