15.5.8 Receive
error
Errors during a receive operation are of three types: parity errors, framing errors, and overrun errors. A
data reception result error flag is set to the UCnSTR register and a reception error interrupt
(INTUCnRE) is output.
During reception error interrupt processing, it is possible to ascertain which error occurred during
reception by reading the contents of the UCnSTR register.
The reception error flag is cleared by writing 0 to it.
Table 15-3:
Reception Error Causes
Cautions: 1. In case of a reception error the reception complete interrupt (INTUCnR) is not
generated. Instead of this a reception error interrupt (INTUCnRE) can be received.
2. Be sure to read the UCnRX register even when a reception error occurs. If the
UCnRX register is not read, an overrun error occurs during reception of the next
data, and reception errors continue occurring indefinitely.
