Writing to a Specific Program Memory Location in C for an ISR

Alan Smith

I'm attempting to use the timer 1 ISR for the ADuC814. In assembly I easily use the ORG directive to write to the address that the PC jumps to when the interupt is set. How do I do the equivalent in C? Any help would be appreciated.

    and would not work for an ISR (as this thread is about)

    He also intimated that he knew how he would have used "ORG" in assembly to get something done and asked about the equivalent in C. In general, only the linker can implement ORG for you. In the special case of ISRs (which I very-well understand he's talking about), I pointed out the interrupt keyword.
