I'm having the time of my life with the jaw-dropping speeds I'm getting with the PIO on the RP2040.
.wrap is like a timewarp and autopull is a gift.
So please don't see me as seeming a bit ungrateful but........
Is there a reason why Autopull can't use X for "pseudo" data if the OSR is empty - in the way that pull noblock can?
I looked at the register info to see if there's a flag which might allow it but didn't find one.
I can live without it - I'm going to use DMA eventually, but just in case anyone knows of an "undocumented" way of doing it? Am I missing something?
Anyway, I'm tremendously grateful to the brilliant engineers who have put this microcontroller together. The documentation is superb too.
