Abstract
An apparatus determines the order of data communication between a plurality of peripheral devices that wish to do so and a central processor unit. Determination is made according to one of a number of selectable priority schedules. The apparatus is modifiable by programmed control so that certain of the peripheral devices can have their priorities reconfigured depending upon changing circumstances.
