OK thanks guys, changing the register worked for me, I just needed to set a flag in the uart callback to let me know when the uart was finished before switching.

I think you will have to uninit the UART and then reconfigure the pins before reinitializing the UART again. As to how you trigger this that is entirely up to you I guess. There's no "recommended" way to do this per se.

Best regards,

Maybe "recommended" is a better word... writing the register is fine for me as long as it doesn't upset the drivers.

Define: "Best".

Personally, I'd just directly write to the PSEL.TXD register.
