You seem to be calling Initialize and not returning from it, The end seems to be a GOTO not a return. Your code is not well commented or threaded. Tom * | __O Thomas C.

This would be the first time that I try to use interrupts, and I have compiled a small and simple piece of code to get started with them. I have attached the ASM-file to this e-mail. I think that the problem is down to me doing something absurdly wrong in my assembler code, although I have no clue to as what it possibly could be. I first suspected it having something to do with me trying to have a button connected to RA3 trigger an interrupt whilst utilizing other RA-ports to flash a couple of LEDs. I proceeded to only flash LEDs on PORTA in the Interrupt Service Routine; but they just never flashed. I don't think that me pushing the button generated an interrupt!
