Note: When a receive error occurs, further receiving is disabled. In receiving, the RDRF flag is

In receiving, the SCI operates as follows.
1. The SCI monitors the receive data line. When it detects a start bit, the SCI synchronizes
2. Receive data is stored in RSR in order from LSB to MSB.
3. The parity bit and stop bit are received.
4. When the RDRF flag is set to 1, if the RIE bit is set to 1 in SCR, a receive-data-full
internally and starts receiving.
After receiving, the SCI makes the following checks:
a. Parity check: The number of 1s in the receive data must match the even or odd parity
b. Stop bit check: The stop bit value must be 1. If there are two stop bits, only the first
c. Status check: The RDRF flag must be 0 so that receive data can be transferred from
If these checks all pass, the RDRF flag is set to 1 and the received data is stored in RDR. If
one of the checks fails (receive error), the SCI operates as indicated in table 13.11.
