13.1.6.1 Parity Error Signal Output

U2C1 register
This timing diagram applies to the case where the direct format is implemented.

NOTE:
The parity error signal is enabled by setting the U2ERE bit in the U2C1 register’ to “1”.
• When receiving
The parity error signal is output when a parity error is detected while receiving data. This is achieved
by pulling the TxD2 output low with the timing shown in Figure 13.1.6.1.1. If the R2RB register is read
while outputting a parity error signal, the PER bit is cleared to “0” and at the same time the TxD2 output
is returned high.
• When transmitting
A transmission-finished interrupt request is generated at the falling edge of the transfer clock pulse
that immediately follows the stop bit. Therefore, whether a parity signal has been returned can be
determined by reading the port that shares the RxD2 pin in a transmission-finished interrupt service
routine.
