Hi All,


While studying The interrupt module in Datasheet of MC9S12XEP100 family 

I had This Doubt " How Interrupt control module decides which interrupt has occured? when Interrupt happens."

For Example 

" If Timer Interrupt occurs How INIT module find this Interrupt was caused by Timer Module ?"


Data Sheet: 


Thanks in Advance
