Abstract
An interface device for a processing unit, allowing a plurality of circuits to be connected to a single input port of the processing unit, capable of acquiring a state value of a circuit of the plurality of circuits, when the circuit is biased, including a plurality, of the same cardinal number, of power sources, each power source being associated with a circuit of the plurality of circuits and capable of biasing same, a switch capable of selectively connecting a single circuit of the plurality of circuits to the associated power source, in such a way as to bias the circuit, and of connecting all of the other circuits to ground, the selection of the biased circuit being controlled by a set of at least one output port of the processing unit.
