SMR is an 8-bit register that specifies the SCI serial communication format and selects the clock
source for the baud rate generator.
Bit
Initial value
Read/Write
The CPU can always read and write SMR. SMR is initialized to H'00 by a reset and in standby
mode.
Bit 7—Communication Mode (C/A A A A ): Selects whether the SCI operates in asynchronous or
synchronous mode.
