Abstract:
An electronic apparatus containinga bus conductor; a load circuit connected to the bus conductor for pulling a potential of the bus conductor towards a quiescent level; stations interconnected by the bus conductor, at least one of the stations comprising a wired logic drive circuit coupled to the bus conductor; an arbitration circuit connected to the wired logic drive circuit for executing an arbitration wherein the stations may each pull the potential against the load circuit; wherein the electronic apparatus comprisesa detector for producing a detection signal when the at least one station wins the arbitration, for switching the load circuit to an increased current supply capability state in response to said detection signal, the load circuit in the increased current supply state supplying a greater current to the bus conductor than during arbitration at times when the potential is pulled against the load circuit and when the potential starts changing towards the quiescent level in the absence of pulling.
