When I view the special function registers using mplab, every register appears to be set to zero. I just can't believe this since when I program two different applications, the PIC (16F87) behaves as if the SFR's have different values, yet when I use mplab to view the SFR's everything is still zero. What have I overlooked? All I want to do is connect the lead from my ICD2 to the PIC and use mplab to read back what the SFR's are set to. Not to much to ask for is it? Thanks
