Hi Champion,

Do you have a paper to summary all the trigger source for illegal ISR?

Thanks

The illegal ISR is only caused by an illegal instruction trap. There is a chapter in the CPU and Instruction Set Reference Guide that lists the events that cause an illegal-instruction trap.

We also have a wiki page that provides some more practical debug tips for ITRAPs:
