Figure 14.12 shows an example of SCI3 operation for reception in clocked synchronous mode. In
serial reception, the SCI3 operates as described below.
1. The SCI3 performs internal initialization synchronous with a synchronous clock input or
2. The SCI3 stores the received data in RSR.
3. If an overrun error occurs (when reception of the next data is completed while the RDRF flag
