Figure 13.9 shows an example of operation for transmission in asynchronous mode. In
transmission, the SCI operates as described below.
1. The SCI monitors the TDRE flag in SSR. If the flag is cleared to 0, the SCI recognizes that
2. After transferring data from TDR to TSR, the SCI sets the TDRE flag to 1 and starts
3. Data is sent from the TxD pin in the following order: start bit, transmit data, parity bit or
4. The SCI checks the TDRE flag at the timing for sending the stop bit.
5. If the TDRE flag is 0, the data is transferred from TDR to TSR, the stop bit is sent, and then
6. If the TDRE flag is 1, the TEND flag in SSR is set to 1, the stop bit is sent, and then the “mark
data has been written to TDR, and transfers the data from TDR to TSR.
transmission. If the TIE bit is set to 1 at this time, a transmit data empty interrupt request (TXI)
is generated. 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.
