Figure 14.8 shows an example of operation for reception in asynchronous mode. In serial
reception, the SCI operates as described below.
1. The SCI monitors the communication line. If a start bit is detected, the SCI performs internal
2. If an overrun error occurs (when reception of the next data is completed while the RDRF flag
3. If a parity error is detected, the PER bit in SSR is set to 1 and receive data is transferred to
4. If a framing error is detected (when the stop bit is 0), the FER bit in SSR is set to 1 and receive
5. If reception is completed successfully, the RDRF bit in SSR is set to 1, and receive data is

ERI interrupt request is generated. Receive data is not transferred to RDR. The RDRF flag
remains to be set to 1.

transferred to RDR. If the RIE bit in SCR is set to 1 at this time, an RXI interrupt request is
generated. Continuous reception is possible because the RXI interrupt routine reads the receive
data transferred to RDR before reception of the next receive data has been completed.
