14.2.9
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 15.2.1, Smart Card Mode Register (SCMR).
SCMR is initialized to H'F2 by a reset, and by putting the device in standby mode or module stop mode. In the H8S/2398,
H8S/2394, H8S/2392, and H8S/2390, however, the value in SCMR is initialized to H'F2 by a reset, or in hardware standby
mode, but SCMR retains its current state when the device enters software 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.
This bit is valid when 8-bit data is used as the transmit/receive format.
Bit 2—Smart Card Data Invert (SINV): When the Smart Card interface operates as a normal SCI, 0 should be written to
this bit.
Bit 1—Reserved: This bit cannot be modified 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 to this bit.
