Abstract
Each of a plurality of programmable master devices having access to a data communication link is assigned a unique address based on the priority of that master device. Each of the plurality of programmable master devices is also interfaced to an access channel. Each of the plurality of programmable master devices can try to gain control of the data link by activating the access channel. The unique address of each programmable master device provides a means by which the highest priority master devices can lock out the lower priority master devices so as to prevent simultaneous transmission on the data link and also prevent loss of high priority data even when a lower priority programmable master device is the device which has activated the access channel.
