Hello;
Occurrences can be generated at every time the output of the 6602 counter change state. That operation is not supported for counting operations.
One thing you can try to do to overcome that is to combine two counters, the first one will have the pulse train to be counted connected to its source and it will be configured as retriggerable pulse train generator. You can configure the pulses to be generated by this counter to have the minimun delay of 2 timebase clocks, and the same width of the pulses that are being counted.
The second counter will receive the output of the first counter on its source and will be configure as simple event counter.
You will catch the occurence generated by the first counter and the value read by the second counter.
There is a drawbacks with this implementation, which is:
There will be a 2 timebase clock pulses delay in between the generation of the occurrence and the event of the pulse on the first counter.
Hope this helps.
