Interrupt Soure

[shawnlammers]

With the 9S12XE512 we configure all unused vectors to point to a dummy handler that then throws an exception to halt the code.

I have the situation where this trap function is being called periodically but I can not figure out which interrupt/vector is being called.

If I place a break point in my interrupt handler is there any way to determine that vector address that caused the call?

Hi,

You can use an interrupt catcher like the one attached.

The variable 'number_of_ISR' will then identify the vector.
