12. Serial Communication Interface
In receiving, the SCI operates as follows:
• The SCI synchronizes with serial clock input or output and synchronizes internally.
• Receive data is stored in RSR in order from LSB to MSB.
• When the RDRF flag is set to 1, if the RIE bit is set to 1 in SCR, a receive-data-full interrupt

REJ09B0395-0400
After receiving the data, the SCI checks that the RDRF flag is 0, so that receive data can be
transferred from RSR to RDR. If this check passes, the RDRF flag is set to 1 and the received
data is stored in RDR. If the checks fails (receive error), the SCI operates as shown in table
12.11.
When a receive error has been identified in the error check, subsequent transmit and receive
operations are disabled.
(RXI) is requested. If the ORER flag is set to 1 and the RIE bit in SCR is also set to 1, a
receive-error interrupt (ERI) is requested.
