11.4.6
Figure 11.7 shows an example of the operation for reception in asynchronous mode. In serial
reception, the SCI operates as described below.
1. The SCI monitors the communication line, and if a start bit is detected, performs internal
2. If an overrun error (when reception of the next data is completed while the RDRF flag is still
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 (when the stop bit is 0) is detected, the FER bit in SSR is set to 1 and receive
5. If reception finishes successfully, the RDRF bit in SSR is set to 1, and receive data is

transferred to RDR. If the RIE bit in SCR is set to 1 at this time, an RXI interrupt request is
generated. Because the RXI interrupt routine reads the receive data transferred to RDR before
reception of the next receive data has finished, continuous reception can be enabled.
