Abstract
A method for arbitration grants access to an ultra high priority device if the ultra high priority device requests access. This access is limited to a selectable number of accesses. Thereafter the ultra high priority device is masked from requesting access for a selectable interval of time during which access may be granted to other devices. The number of assess and the interval of masking are preferably controlled by memory mapped data registers loaded into dedicated counters.
