Section 14 Serial Communication Interface (SCI)
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 standby mode or module stop mode.
Bit 7—Communication Mode (C/A A A A ): Selects asynchronous mode or clocked 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
clocked synchronous mode, a fixed data length of 8 bits is used regardless of the CHR setting.
