Abstract
There is disclosed a wired-AND bus emulator circuit that allows any node to prevent propagation of information through the node. A controller can command all other controllers on the bus to break the bus thereby allowing the controller to determine the topology and possibly dynamically program the address of each controller on the bus. By allowing a controller to determine the bus topology, and possibly program the address of each other controller, the bus designer can configure the bus in a topology that is physically convenient. Additionally, the installer is not required to program each node with a unique address.
