In receiving, the SCI operates as follows:
• The SCI monitors the communication line. When it detects a start bit (0 bit), the SCI
• Receive data is stored in RSR in order from LSB to MSB.
• The parity bit and stop bit are received.
• When the RDRF flag is set to 1, if the RIE bit is set to 1 in SCR, a receive-data-full interrupt

synchronizes internally and starts receiving.
After receiving these bits, the SCI carries out the following checks:
⎯ Parity check: The number of 1s in the receive data must match the even or odd parity
⎯ Stop bit check: The stop bit value must be 1. If there are two stop bits, only the first is
⎯ Status check: The RDRF flag must be 0, indicating that the receive data can be transferred
If these all checks 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 shown in table 12.11.
