SMR is used to set the SCI’s serial transfer format and select the baud rate generator clock source.
Some bit functions of SMR differ between normal serial communication interface mode and Smart
Card interface mode.

Description
Communication Mode
0: Asynchronous mode
1: Clocked synchronous mode
Character Length (enabled only in asynchronous
mode)
0: Selects 8 bits as the data length
1: Selects 7 bits as the data length. LSB-first is
In clocked synchronous mode, a fixed data length
of 8 bits is used.
Parity Enable (enabled only in asynchronous
mode)
When this bit is set to 1, the parity bit is added to
transmit data before transmission, and the parity
bit is checked in reception. For a multiprocessor
format, parity bit addition and checking are not
performed regardless of the PE bit setting.
Parity Mode (enabled only when the PE bit is 1 in
asynchronous mode)
0: Selects even parity
1: Selects odd parity
