• Reception error causes
When reception errors occur, perform the following procedures depending upon the kind of error.
• Parity error
• Framing error
• Overrun error
Caution If a receive error interrupt occurs during continuous reception, read the contents of the UCnSTR
If false data is received due to problems such as noise in the reception line, discard the received data and retransmit.
A baud rate error may have occurred between the reception side and transmission side or the start bit may have
been erroneously detected. Since this is a fatal error for the communication format, check the operation stop in the
transmission side, perform initialization processing each other, and then start the communication again.
Since the next reception is completed before reading receive data, 1 frame of data is discarded. If this data was
needed, do a retransmission.
