Abstract:
1. A device identifier establisher for establishing a device identifier (ID) for a device configured in a serial interconnection configuration having a plurality of devices, the device identifier establisher comprising: a clock input for receiving a clock signal; an ID producer for producing a device ID in response to an M-bit input signal received at an input of the device, the M-bit input signal received at the input of the device in response to an assertion of an input enable signal and including an N-bit ID corresponding to the device ID, and outputting an M-bit output signal in response to an assertion of an output enable signal, the M-bit output signal including an N-bit data corresponding to the device ID through an output of the device to a subsequent device in the serial interconnection configuration synchronously with the clock signal, M and N being an integer that is one or greater than one; an ID register for storing the N-bit data as an assigned ID for the device; and a control input for receiving a control signal, the ID register being configured to store the N-bit data as an assigned ID in response to the received control signal and the received control signal being produced in response to the output enable signal.
