Eriks comment: done in SW, this does not cause problems, even if you miss part of this oscillation stuff, all it does is inc or dec the result by 1.

I expect to sample the states approx all 3..5usecs using the Cygnal F300. Enough for most motor encoders. For exp. 6000rpm 500 pulses per revolution gives 1000states x 100r/sec =100'000states per sec to observe
