User feedback
- smunaut👑: Surprisingly I was able to get "shift register" behavior out of both the internal clock and dual-phase clock version. This is just twiddling signals in micropython so the timings are terrible and not to be trusted, but the fact you can pipe data in and get it out 36 cycles later is already nice to see. Also, I said "surprisingly" because AFAIR this wasn't working in simulation ...
