https://devzone.nordicsemi.com/f/nordic-q-a/119367/uart-error-are-not-clearedHello, I&#39;m trying to detect a UART_ERROR_BREAK on an USB ACM CDC interface of the nRF5340 using NCS2.7. The returned error code is always 0xffffffa8. How do I clear the error? Furthermore, is there a way to generate a BREAK-Error?
