Coldfire MCF 5307 IRQ7 Initialization/ISR

I am currently working to modify firmware on a Coldfire 5307, and we are needing to use the NMI IRQ7(pin68) pin for power failure. This will only be used in last resort situations.


I have endless documentation for setting up everything else imaginable on the 5307, just nothing substantial enough to even get started setting up IRQ7. Any help from someone that has any experience programming IRQ7 on a coldfire 5307 would be greatly appreciated, thanks much!
