The RHA specifies the address of the handler associated with the interrupt. The availability of an RHA for each interrupt allows the Nios® II processor to jump directly to the interrupt handler, reducing interrupt latency.

The RHA for each interrupt is typically software-configurable. The method for specifying the RHA is dependent on the specific EIC implementation.

If the Nios® II processor is implemented with an MMU, the processor treats handler addresses as virtual addresses.
