1. A device for a single wire digital bus, comprising:
an interface for the single wire digital bus, the interface configured to receive on the single wire digital bus a request to arbitrate for an address and transmit first device specific data on the single wire digital bus upon receipt of the request to arbitrate for the address; and
a control circuit configured to monitor for any further device that concurrently transmits further device specific data on the single wire digital bus while the interface transmits the first device specific data on the single wire digital bus and the control circuit is configured to use the arbitrated address for a further transmission on the single wire digital bus if the control circuit does not detect any further device that concurrently transmits further device specific data on the single wire digital bus while the interface transmits the first device specific data on the single wire digital bus.
