Section 14 Serial Communication Interface 3 (SCI3)
14.4.3
Figure 14.5 shows an example of operation for transmission in asynchronous mode. In
transmission, the SCI3 operates as described below.
1. The SCI3 monitors the TDRE flag in SSR. If the flag is cleared to 0, the SCI3 recognizes that
2. After transferring data from TDR to TSR, the SCI3 sets the TDRE flag to 1 and starts
3. The SCI3 checks the TDRE flag at the timing for sending the stop bit.
4. If the TDRE flag is 0, the data is transferred from TDR to TSR, the stop bit is sent, and then
5. If the TDRE flag is 1, the TEND flag in SSR is set to 1, the stop bit is sent, and then the “mark
6. Figure 14.6 shows a sample flowchart for transmission in asynchronous mode.

Continuous transmission is possible because the TXI interrupt routine writes next transmit data
to TDR before transmission of the current transmit data has been completed.
