Claim Text:
1. A method for managing the operation of a slave circuit operating in a slave mode, the circuit connected to a bus having a plurality of wires and being configured to impose a plurality of logic levels on the bus, wherein a priority logic level of the plurality of logic levels is selected to be imposed at a given time, the method comprising: imposing, by the slave circuit, the priority logic level on a first wire of the bus; while imposing, detecting, by the slave circuit, a possible conflict on the first wire resulting from a forcing, external to the slave circuit, of the first wire to an other logic level, wherein the other logic level comprises a voltage that does not correspond to a logic level of the plurality of logic levels, and detecting the conflict comprises detecting, by the slave circuit, that the voltage of the other logic level is greater than the priority logic level being imposed by the slave circuit; and upon detecting a conflict, placing the slave circuit in a state stopping, wherein the slave circuit listens to the bus but does not send any data over the bus in the stopping state.
