Reading frequency input (i.e. - flow meter) with BL2600

I’ve seen the BL2600 be used to read a fairly slow pulse train (say 50-100 hz) coming off a motion controller but I need to read a flow meter frequency now that’s 10 KHz or higher. The code we did for a motion controller basically continually polled a register that was set to trigger on a leading edge of a digital input channel. The motion controller pulse train coming in was slow enough that the code could loop fast enough to not miss a state change so that worked. But there’s not really any way to read a frequency signal that’s coming in at say 10KHz or faster using a BL2600 is there?

Timely. I actually need to do the same with a BL2100. I’ll let you know what I find - please do the same.
