MOD 54415 IRQ 7 assembly code

Has anyone successfully coded IRQ 7 in assembly? I'm not the strongest with coldfire assembly, and was wondering if anyone had attempted it, maybe even something I could look at. I need it to only shut down my system, that's it. Thanks!

I'd recommend starting with C (and the interrupt macro) and then optimizing the disassembled output.
Perhaps this might be something fun to do this evening...

Did you say fun? I know not this word....lol
It was suggested to me that I look at the disassembly for a different IRQ pin and work from there. It's a slower method, but I think I can learn assembly slowly from there. I just was looking for a snippet that I could play/work with, modify and test until I got it right. I guess I'll try the disassembly first.
