Section 15 Serial Communication Interface (SCI, IrDA)
15.2.5
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, watch mode, subactive mode, subsleep
mode, and module stop mode.
Bit 7—Communication Mode (C/A A A 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.
