Thanks to every one for your help. Sorry for the delay in responding, our internet connection was down for 12 hours. I am trying to count the number of switch closures of a very fast reed switch. TMR1 is counting edges on T1CKI, just as it's supposed to. Ultimately,this switch will wake the program from SLEEP, and resume counting. I haven't as yet quite figured out how to use DT's Instant Interrupts to do this, but in doing so, maybe this will help with the "debounce" problem.

For now, I may use Paul's idea of just counting the pin, or try using falingtrea's RC filter.

Thanks again.
