1. PHI1 IS THE SAME FREQUENCY AS THE SYSTEM CLOCK; HOWEVER, IT DOES NOT HAVE THE SAME TIMING.
2. A = PAI SIGNAL AFTER THE SYNCHRONIZER.
3. B = “A” AFTER THE DIGITAL FILTER.
4. THE EXTERNAL LEADING EDGE CAUSES THE PULSE ACCUMULATOR TO INCREMENT AND THE PAIF FLAG TO BE SET.
5. THE COUNTER TRANSITION FROM $FF TO $00 CAUSES THE PAOVF FLAG TO BE SET.
