Xbees are serial, so if you do any kind of ISR work (whether using raw pin state counts or RTCC or PORT B interrupt pin states, you'll need to move the serial comm routines into the ISR. SXB serin and serout depend on consistent timing of cycles un-interrupted (or fold it into TASKs but I think the overhead there may be too stiff).

Or go back to Bean what suggested -- doing a COUNT in the mainline (if you can afford to take time off from counting pulses to do your serial comms and other work).
