Hi CheePin,

Thanks for the reply.

I did not test again, just to detect the combination of both rx_patterndetect and 0xBC.

Well, it did not trigger for more than 30 mins.

Therefore I suppose it's kind of timing issue related to SignalTap..

Do you think it's possible?

BRs,

Johnson

Hi Johnson, Based on the currently observation, frankly speaking, we could not really narrow down the root cause if it is related to timing issue related to the signaltap. If you does not plan to further pursue the testing, you would need to perform thorough testing with your application to ensure it is meeting your expectation. For example, no issue with the received data and no word alignment issue. Thank you. Best regards, Chee Pin
