Description
1
Un0OER
This bit is used to indicate an overrun error in UARTn0 full-duplex communication mode and
half-duplex communication mode.
This bit becomes "1" if the next data is received before reading the previous receive data in
the serial communication unit n transmit/receive buffer L (SDnBUFL).
The Un0OER bit is forcibly reset to "0" by writing “1” to this bit.
The Un0OER is fixed to "0" in the transmit mode.
0: The overrun error has not occurred (initial value)
1: The overrun error has occurred
0
Un0FER
This bit is used to indicate a framing error in UARTn0 full-duplex communication mode and
half-duplex communication mode.
This bit becomes "1" when an error occurs in the stop bit and holds “1” until it is cleared by
the software.
The Un0FER bit is forcibly reset to "0" by writing “1” to this bit.
The Un0FER is fixed to "0" in the transmit mode.
0: The framing error has not occurred (initial value)
1: The framing error has occurred
[Note]
Ÿ
The Un0OER bit becomes "1" if the previous receive data is not read even after reception is stopped by
the Un0EN bit and restarted. Therefore, set the Un0EN bit to “1” after reading the SDnBUFL, or when the
reception is completed, be sure to read the SDnBUFL even if the data is unnecessary.
Ÿ
When an error occurs in the start bit, the state returns to the reception waiting state.
Ÿ
Do not write the Un0FER bit, Un0OER bit, Un0PER bit and Un0FUL bit by using the bit symbol. Write
them by the byte-access.
