    Can you use the SWD as a UART for debugging purposes? Or is SWD specific to register writes and reads and not made to be used within a program?

    Thanks!

    Google search for "SWD AS UART". You'll find lots of articles, but no obvious easy answers.

    You are probably thinking about SWO/ITM viewer.

    Better yet, google RTT or J-Scope.
