ABSTRACT:
To enable a determined mode of operation, out of several possible modes, to be dictated from the exterior of an integrated circuit, there is provided a specific pin and a detector that is connected to the pin and is capable of detecting a logic level 0 or 1 or a high impedance state at this pin. The detector includes several switches and a resistor. It works in two successive phases and consumes no current at rest. A register memorizes the logic level of the pin during the two phases, and a decoder determines the state of the pin from the two memorized logic levels.
