Hello.
Please explain how to detect errors in UART interrupt-driven operation.
If an error is detected by calling `uart_err_check()`, is it necessary to clear the error flag (?)?
I checked the API documentation, and while it states that `uart_err_check()` detects errors,
there was no mention of how to handle the flag after an error is detected.
I'd also like to know the range of possible values for the error data.
