Thanks for answer.
I need the tuning to make two pulses 3.5uS broad spaced 12uS +/- 0.1uS!
The single pulses is made by writing 15 points from a table and the spacing with 10uS delay + writing to PORTD to adjust the delay. This pulses is send 12 times spaced 30uS.
Then I will try to find the error another place.
