Question regarding hardware serial and GPIO

[Andy Wood]

Thanks for the replies. The UART TX pin cannot be used fro GPIO in this case.

From my experience, you can use the TX pin as an input. This same experienced is shared and discussed on the Microchip forum. However, I don't think you should do it if it can be avoided. Again, I have some prototypes which use it that way and they work without issues; but it seems like undocumented (likely unsupported).
