... between the PIC1 8 and the other PIC microcontroller processors is the inclusion of the negf (Fig. 7 .50 ) instruction, which can negate any register in the PIC1 8’s register space. The single instruction ... zeroed out (and become nops) and then are programmed into the PIC microcontroller. Before making the change, the programmer will issue an error message at...
