Calculating Program Memory Checksums Using a PIC16F87X

INTRODUCTION Many applications require the microcontroller to calculate a checksum on the program memory to determine if the contents have been corrupted. Until now, the only family of PICmicro® microcontrollers to have the capability to read from program memory are the PIC17CXXX devices. The PIC
