Invoking Interruption using PLU module (LPCxpresso55S69)

I would like to invoke a  hardware interruption whenever there is a change in the PLU Inputs values (PLU_INs).


I have used the NVIC_EnableIRQ() from the CMSIS access NVIC functions.

Also I checked the PLU interrupt priority and it is 0.

But whenever I change the PLU_IN values, (from 0V to ),  nothing occurs, no execution of the PLU_IRQHandler(). No interruption happen. I tried to manually pend the interruption (using the SW) only then the PLU_IRQHandler() is executed. 


Any idea about what I maybe missing?

Any example deploying interruptions? 

When does the SysTick has to do with peripheral interruption? 


Thank you in advance.
