16.3.4
TSR is a shift register that transmits serial data. To perform serial data transmission, the SCI first
transfers transmit data from TDR to TSR, then sends the data to the TxD pin. TSR cannot be
directly accessed by the CPU.
16.3.5
SMR is used to set the SCI’s serial transfer format and select the clock source for the on-chip baud
rate generator.

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.
fixed and the MSB of TDR is not transmitted in
transmission.
