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

SCMR is initialized to H'F2 by a reset and in hardware standby mode. It retains its previous state

in module stop mode, software standby mode, watch mode, subactive mode, and subsleep 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.

This bit is valid when 8-bit data is used as the transmit/receive format.

Bit 3

SDIR

Description

TDR contents are transmitted LSB-first

(Initial value)

Receive data is stored in RDR LSB-first

TDR contents are transmitted MSB-first

Receive data is stored in RDR MSB-first
