In serial reception, the SCI operates as described below.
1. The SCI performs internal initialization in synchronization with serial clock input or output.
2. The received data is stored in RSR in LSB-to-MSB order.
3. If the RIE bit in SCR is set to 1 when the RDRF flag changes to 1, a receive-data-full interrupt
Figure 15.19 shows an example of SCI operation in reception.
Simultaneous Serial Data Transmission and Reception (Synchronous Mode): Figure 15.20
shows a sample flowchart for simultaneous serial transmit and receive operations.
The following procedure should be used for simultaneous serial data transmit and receive
operations.

After reception, the SCI checks whether the RDRF flag is 0 and the receive data can be
transferred from RSR to RDR.
If this check is passed, the RDRF flag is set to 1, and the receive data is stored in RDR. If a
receive error is detected in the error check, the operation is as shown in table 15.11.
Neither transmit nor receive operations can be performed subsequently when a receive error
has been found in the error check.
(RXI) request is generated.
Also, if the RIE bit in SCR is set to 1 when the ORER flag changes to 1, a receive-error
interrupt (ERI) request is generated.
