UART assign the TX and RX to same pin in nRF52

Hi Team

I see below information in the spec of nRF52840.  Can I assign both the TXD and RXD signal to same pin? Thank you.

Regards

Hi Victor

You should not assign the TX and RX signals of a peripheral to the same pin. It might seem like it works, but the behavior is undefined, and is likely to cause issues down the road if you do. It is strongly recommended to avoid doing this, hence the warning in the product specification.

Best regards,

Simon
