Hi, I'm using the P89LPC932A1 and attempting to read the global checksum using IAP during normal program execution. I have used this knowledgebase article as my guide: http://www.keil.com/support/docs/2554.htm So basically, I added this function to my code:
long unsigned IAP_ReadGlobalCRC (void) { ACC = 6; // MOV A,#06H return ((unsigned char (code *)(void)) 0xFF03)(); // LJMP 0FF03H }
