Visiuser,
An AHB slave never *has* to give a SPLIT or a RETRY response; these responses are simply optimisations such that a slave which knows it is going to take a long time to provide the requested data can, potentially, offer improved overall system performance.
It would be perfectly legal for a simple AHB slave to only implement OK (as an aside, AHB-Lite only supports OK and ERROR).
