Section 19 Serial Communication Interface (SCI, CRC)
19.6.4
Figure 19.21 shows an example of SCI operation for reception in clocked 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 in SSR
3. If reception finishes successfully, the RDRF bit in SSR is set to 1, and receive data is
Transfer 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 19.22 shows a sample flowchart
for serial data reception.

time, an ERI interrupt request is generated. Receive data is not transferred to RDR. The RDRF

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 processing routine reads the receive data transferred to
RDR before reception of the next receive data has finished, continuous reception can be
enabled.
