In receiving, the SCI operates as follows:
1. The SCI monitors the communication line. When it detects a start bit (0), the SCI synchronizes
2. Receive data is shifted into the RSR in order from the LSB to the MSB.
3. The parity bit and stop bit are received. After receiving these bits, the SCI makes the following
4. After setting RDRF to 1, if the receive-data-full interrupt enable bit (RIE) is set to 1 in the
Figure 12.7 shows an example of SCI receive operation in the asynchronous mode.

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 stop bit
c. Status check. RDRF must be 0 so that receive data can be loaded from the RSR into the
If the data passes these checks, the SCI sets RDRF to 1 and stores the received data in the
RDR. If one of the checks fails (receive error), the SCI operates as indicated in table 12.16.
Note: When a receive error occurs, further receiving is disabled. While receiving, the RDRF
bit is not set to 1, so be sure to clear the error flags.
