Figure 14.21 shows an example of SCI operation for reception in clock synchronous mode. In
serial reception, the SCI operates as described below.
1. The SCI performs internal initialization in synchronization with a synchronization clock input
2. If an overrun error (when reception of the next data is completed while the RDRF flag is still
3. If reception finishes successfully, the RDRF bit in SSR is set to 1, and receive data is
Reception cannot be resumed while a receive error flag is set to 1. Accordingly, clear the ORER,
FER, PER, and RDRF bits to 0 before resuming reception. Figure 14.22 shows a sample flowchart
for serial data reception.

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.
