SMR is used to set the SCI's serial transfer format and select the baud rate generator clock source.
Some bits in SMR have different functions in normal mode and smart card interface mode.
• When SMIF in SCMR = 0
• When SMIF in SCMR = 1

Description
Communication Mode
0: Asynchronous mode
1: Clocked synchronous mode
Character Length (valid only in asynchronous mode)
0: Selects 8 bits as the data length.
1: Selects 7 bits as the data length. LSB-first is fixed and
In clocked synchronous mode, a fixed data length of 8
bits is used.
Parity Enable (valid 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.
the MSB (bit 7) in TDR is not transmitted in
transmission.
