I'm not totally sure what you're asking since your message was a bit
unclear, but how about using a CCP module for capturing the pulses for the
frequency counter.  These are great for measuing pulse period since the
timer value is captured in hardware when the pulse comes in, then the
software can take some time to read it as long as it gets there before the
next pulse.
