Documentation on interrupt handling (MC1321x)

I am having difficulty handling interrupts in my MC13212 and I'd like a pointer to some document describing how to do it. I tried to follow the help section of CodeWarrior, which seemed very helpful, but the codes does not work.

For example, it seems that to have a push button trigger a KBI event one needs to only enable the KBI functionality by setting KBISC and KBIPE appropriately and have the following to show that the interrupt happened:

interrupt 22 void PB_interrupt(void)

{

//light led here that will stay lit to show that code executed

}

I am trying not to modify the prm file as I don't understand what it does. Any pointer to documentation on that would also be appreciated.

Thanks for your help,

drdr

Did you set up the vector addresses table so that there's a pointer to your PB_interrupt(void) ?
