Abstract
A method for dynamically reconfiguring control of a data bus when an initial device acting as a bus master fails or become inoperative. Each device connected to the data bus checks for the logical address of either its next higher or next lower neighbor; and the initial device acting as bus master is arbitrarily assigned the highest or lowest available logical address respectively. In either instance, the logically next lower or logically next higher device, respectively, may see a device at a logical address that is lower or higher than its own, thereby indicating that the initial device acting as bus master has become inoperative. Thereafter, the next available device able to act as bus master promotes itself to act as bus master, including reassigning itself to the highest or lowest available logical address, respectively.
