16.3.4
TSR is a shift register that transmits serial data. To perform serial data transmission, the SCI first
automatically transfers transmit data from TDR to TSR, and 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 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
In clocked synchronous mode, a fixed data length of 8
bits is used.
and the MSB (bit 7) in TDR is not transmitted in
transmission.
