5. Serial mode register (SMR)
SMR is an 8-bit register used to set the serial data transfer format and to select the clock source for
the baud rate generator.
SMR can be read or written by the CPU at any time.
SMR is initialized to H'00 upon reset, and in standby, watch or module standby mode.
Bit 7: Communication mode (COM)
Bit 7 selects whether SCI3 operates in asynchronous mode or synchronous mode.

Bit 6: Character length (CHR)
Bit 6 selects either 7 or 8 bits as the data length to be used in asynchronous mode. In synchronous
mode the data length is always 8 bits, irrespective of the bit 6 setting.
