ABSTRACT:
In a network node attached to a serial bus, a first count value is incremented beginning with the start timing of a child notify signal transmitted from the node to the bus until the end timing of a parent notify signal received by the node from said bus. The first count value represents the turnaround time of signals between the node and a node attached to the remote end of the serial bus. Normally, signals from the serial bus are supplied to a higher layer. Instead of the received bus signal, an idle signal is supplied to the higher layer for an interval beginning with the end timing of a packet transmitted from the higher layer to the bus until the interval corresponds to the turnaround time.
