Abstract
Device identification generation in electronic devices to allow external control, such as selection or reprogramming, of device identification for bus communications identification, is disclosed. In this manner, device identifications of electronic devices coupled to a common communications bus in a system can be selected or reprogrammed to ensure they are unique to avoid bus communications collisions. In certain aspects, to select or reprogram a device identification in an electronic device, an external source can be electrically coupled to the electronic device. The external source closes a circuit with a device identification generation circuit in the electronic device. The closed circuit provides a desired electrical characteristic detectable by the device identification generation circuit. The device identification generation circuit is configured to generate a device identification as a function of the detected electrical characteristics of the closed circuit from the external source.
