In receiving, the SCI operates as follows.
The SCI synchronizes with serial clock input or output and initializes internally.
Receive data is stored in RSR in order from LSB to MSB.
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 check does not pass (receive error), the SCI operates as indicated
in table 13-11.
After setting the RDRF flag to 1, if the RIE bit is set to 1 in SCR, the SCI requests a receive-
data-full interrupt (RXI). If the ORER flag is set to 1 and the RIE bit in SCR is also set to 1,
the SCI requests a receive-error interrupt (ERI).
