An integrated circuit (IC) configured to operate as a slave on an inter-integrated circuit (IC) or IC compatible bus. The IC is further configured to receive an address through the IC bus and store the received address in a register, so as to be identified by the address. A method of address assignment in a master/slave system, the system comprises at least one master, a plurality of slaves, and an IC or IC compatible bus. The method comprises sending a first address by the master on the IC bus to a first of the plurality of slaves and storing the first address on the first slave to identify the first slave by the first address. The method further comprises sending a second address by the master on the IC bus to a second of the plurality of slaves and storing the second address on the second slave to identify the second slave by the second address. The steps of sending and storing are repeated until all slaves of the system have stored an address.

In a node failure detection technique at least one supervisory data processing node periodically transmits a receipt acknowledge data packet to each other data processing node. The supervisory data processing node determines a data processing node has failed upon failure to receive a return acknowledge data packet. This acknowledge data packet preferably includes health data concerning its current health operating status. The supervisory data processing node sends a reset data packet to any failed data processing node determined. If the reset does not return the data processing node to normal operation, then routing data at neighboring data processing nodes is altered to route data packets around the failed node.
