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 (RXI) request is
Figure 14-19 shows an example of SCI operation in reception.

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 14-11.
Neither transmit nor receive operations can be performed subsequently when a receive error has been found in the
error check.
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.
