Method for switching from a first operating condition of an integrated circuit to a second operating condition of the integrated circuit

摘要

The invention provides a method for switching from a first operating condition of an integrated circuit to a second operating condition of the integrated circuit differing from the first operating condition. To that end, the output signal generated at a circuit output is externally overwritten. The inventive method or the inventive integrated circuit have the advantage that the switching from one operating condition into another operating condition of the integrated circuit can be implemented in a very simple way but with a high immunity to interference. The switching can be very easily initiated as needed because the only thing needed is the application of a voltage level—which is already available in the system—to an output of the integrated circuit. Furthermore, the selection of a circuit output assures that there is a high certainty that the switching condition will not accidentally occur because this is largely precluded by the standard and usually prescribed external interconnection of a circuit output.
