15.2.5
SCSMR1 is an 8-bit register used to set the SCI's serial transfer format and select the baud rate
generator clock source.
SCSMR1 can be read or written to by the CPU at all times.
SCSMR1 is initialized to H'00 by a power-on reset or manual reset, in standby mode, and in the
module standby 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,
