When a reception error occurs, perform the following procedure according to the kind of error.
• Parity error
• Framing error
• Overrun error
Caution In reception, be sure to read the UAnSTR register before completion of the next reception to
If false data is received due to problems such as noise on the reception line, discard the received data and
retransmit.
A baud rate error may have occurred between the reception side and transmission side or a start bit may have
been erroneously detected. Since this is a fatal error for the communication format, check that operation on the
transmission side has stopped, initialize both sides, and then start the communication again.
1 frame of data is discarded because the next reception is completed before data was read from the receive
buffer. If this data was needed, retransmit the data.
