Hi,

yes, it works. We use the BREAK detection and by now it works fine. We had one design compiled with Q8.1 and now on Q10.0.

Both work.

As we haven't bidirectional UART, we have an extra PIO which switches the the RXD and TXD pin to the right external wire.

So we cannot transmit and receive simultaneously.

Make sure that your device is in receiving mode when you try to detect the BREAK.
