How do I verify the ID locations in an 18F4550 using an ICD2. I can write source code to put data in the locations, and I can see the data in the hex file, but how do I verify that the locations in the PIC have been programmed? I am mainly interested in verifying that production products have been programmed with the correct software version, which I would like to put in the ID locations.
