12.6.4
Figure 12.21 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 synchronous with a synchronous clock input or output,
2. If an overrun error occurs (when reception of the next data is completed while the RDRF flag
3. If reception is completed 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 12.22 shows a sample flow chart
for serial data reception.
When the internal clock is selected during reception, the synchronization clock will be output until
an overrun error occurs or the RE bit is cleared. To receive data in frame units, a dummy data of
one frame must be transmitted simultaneously.

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 finished.
