14.2.5
SMR is an 8-bit register used to set the SCI’s serial transfer format and select the baud rate
generator clock source.
SMR can be read or written to by the CPU at all times.
SMR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode
and module stop mode it retains its previous state.
Bit 7—Communication Mode (C/A): Selects asynchronous mode or synchronous mode as the
SCI operating mode.

Bit 6—Character Length (CHR): Selects 7 or 8 bits as the data length in asynchronous mode. In
synchronous mode, a fixed data length of 8 bits is used regardless of the CHR setting.
