Does anyone know how (or if) you can set up a break point in MPLAB that will stop program when a register = predetermined value. Specifically, I want the program to stop where RC2IE is being cleared for PIC17C756A and using MPLAB ICE 2000. If MPLAB does not have such a facility, do you have any tips for achieving this.
