Interrupt RPM and Taylors Elapsed time on 18F4620

[Bruce]

You don't need the bit tests in Direction since you have CCP_INT (or Direction) set as a high-priority interrupt, and you have ClockCount set as a low-priority interrupt.

Direction will be jumped to automatically when the CCP interrupt fires. ClockCount will be jumped to automatically when the TMR3 interrupt fires. Note that your low-priority interrupt can be interrupted by the high-priority one.
