Abstract:
In a data network having a bus to which are connected a given node, a parent node and a child node, and wherein arbitration over acquisition of the bus is performed before data is communicated between nodes, a method for controlling transition to an initial state in a self identification phase in which said given node is enabled to respond to an arbitration signal received from said parent node, comprising the steps of:receiving at said given node a SELF_ID packet representative of said child node; receiving at said given node said arbitration signal (SELF_ID_GRANT) from said parent node, thereby enabling said given node to transmit to said parent node a SELF_ID packet representative of said given node; and assuming said initial state in the self identification phase at said given node, from which said SELF_ID packet is permitted to be transmitted from said given node to said parent node, if the reception of said arbitration signal from said parent node is completed at said given node.
