I just got confused about INTC function INTC_register_interrupt(),
so my question is can there be only one interrupt routine been registered with one IRQ?
I think any IRQ can only have one interrupt routine registered.
well, as soon as interrupt ocurs, processor must know without any ambiguity where to step next and based upon any condition check in ISR further steps to followed can be determined.
so there can be one and only one ISR regitered with any IRQ
