Abstract:
1. A device for use as a slave device in a system having a master device and at least one slave device coupled to a serial bus comprising: an interface, to connect to a serial bus to receive a communication from a master device over the serial bus and generate signals in response thereto, the interface comprising a storage device to provide a bus address by which the master device addresses the device, wherein the bus address has a fixed base portion and a configurable portion; an output at which an output signal of the device is provided in response to the interface generated signals; a comparator circuit, coupled to the output, to determine a state of the output and having a comparator circuit output at which the state of the output is provided; and control circuitry, coupled between the storage device and the comparator circuit output, to use the state provided at the comparator circuit output to configure the configurable portion as a unique identifier for the device.
