Hi Matthias, what is your proposal to generate a (1/100us) clock (for e.g. the output of a bit pattern ) in amforth? (as you wrote, the timer int. isn't usable for such speed) What speed can I expect when I use the word pause? Is there a guarantee how often the word is called per ms? Because the pulses should come in a certain time distance.
