zero/null/no delay pulse generation on PCI 6602?

Hi!

I need to configure a pulse generator to mantain a high output for N pulses sourced by a flow meter. (So that I can use another counter to measure this time.)

Is it possible to generate such a pulse without any delay ticks (null/zero delay)??

So that I could arm this measurement and I wouldn't need to wait this dull pulse before the N pulses I want to measure their time duration.

Thanks!
