On imp003, we’re using uart.UVGD in NO_CTSRTS mode. Because D & G are now unused, we would like D for its state-change callback functionality.
If we configure uart.UVGD and then configure D as an input with a callback function, should we expect it to work?
Might we run into issues where:
- Activity on PinD would confuse the uart (unlikely, because we’ve told it to ignore rts/cts)?
- The uart does something to PinD at some point either reconfiguring it or causing unpredictable states?
