There are multiple ways to service an interrupt depending on how much of the hardware assistance offered by the VIM software wants to take advantage of. For IRQs, it is recommended to use 3.4.1 IRQ through the Vector Interface, but 3.4.2 or 3.4.3 (if a user wants to implement a fully software prioritization scheme) may be used as alternatives. For FIQs, it is recommended to use 3.4.4 FIQ, but 3.4.5 may be used as an alternative.
