SCMR selects LSB-first or MSB-first transfer by means of bit SDIR. Except in the case of
asynchronous mode 7-bit data, LSB-first or MSB-first transfer 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 15.2.1, Smart Card Mode Register (SCMR).
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.
