STATIC ADDRESS ALLOCATION BY PASSIVE ELECTRONICS

摘要

A bus node IC comprises at least one static address selection terminal and a detecting circuit for detecting a state of the static address selection terminal, and a communication circuit adapted for determining a node address identifier taking the detected state into account. The detecting circuit is adapted for detecting the state by determining an electrical property of a passive electronic component when connected to the static address selection terminal. The communication circuit is adapted for receiving/transmitting data over the data bus in accordance with a first communication protocol using the node address identifier for identification of the IC, and for receiving/transmitting data over said data bus in accordance with a second communication protocol using a further node address identifier for identification of the IC, wherein the communication circuit is adapted for configuring the further node address identifier by using data received using the first protocol.
