Joe, OK. My understanding of the PWM is that once setup it continues to=20 output what ever all by its self with no input from the rest of the code=20 being necessary. So why not send this pulse to a gate and use a pin to=20 open that gate and send the pulse on to the count control gate when it=20 is necessary? OK, I see. So you just execute 5 or 6 NOPs for the reset pulse=20 since it isn't critical? Thanks, rich!
