Section 13 Serial Communication Interface (SCI)
13.6.3
Figure 13.19 shows an example of SCI operation for transmission in clocked synchronous mode.
In serial transmission, the SCI operates as described below.
1. The SCI monitors the TDRE flag in SSR, and if the flag is 0, the SCI recognizes that data has
2. After transferring data from TDR to TSR, the SCI sets the TDRE flag to 1 and starts

transmission. If the TIE bit in SCR is set to 1 at this time, a transmit data empty interrupt
(TXI) is generated. Continuous transmission is possible because the TXI interrupt routine
writes the next transmit data to TDR before transmission of the current transmit data has been
completed.
Note: In simultaneous transmit and receive operations, the TE and RE bits should both be cleared
