I would use one of the following methods:
- Connect the pulse input pin to the RTCC pin. Choose the appropriate signal
edge and test the RTCC value repeatedly until it increments.
- Connect the pulse input pin to the rb0/int and handle the event in an
interrupt routine, testing the INT-Flag.
- put a counter-IC or a JK-Flipflop between the PIC-pin and the input line,
so that an input pulse produces a level change at the PIC-pin.

I have not tested any of these techniques, so maybe something does not work
as I thought.

Siggi.
