Modulating uart output

If you want an event for every bit, I would think a "hack" is needed: Split the outgoing UART signal so that one line go to a GPIO. GIPOTE can then be used to trigger on rising edge/falling edge or both. That may be a little closer to what you want to do. Perhaps it is possible to combine it with some logic as well, if needed.

It looks to me that this event is geared towards the entire byte transmission, not the individual bits of the bytes. I am looking for an event that fires after the transmission of every bit in the byte

I think this is not possible?

Yes, it should be possible to make f.ex the TX UART sent event (EVENTS_TXDRDY) trigger a PWM task using PPI.

I would recommend you to take a look at the PPI example in the SDK to get at starting point.
