| To properly handle the interrupts the processor must recognise the source of the interrupt. Different code should be executed when the interrupt is signalled by a network controller, different if the source of the interrupt is a timer. The information on the interrupt source is provided to the processor by the interrupt controller or directly by the peripheral. | To properly handle the interrupts the processor must recognise the source of the interrupt.
