A method of switching from a first operational state of an integrated circuit to a second operating state of the integrated circuit

According to the invention a method for switching from a first operational state of an integrated circuit is provided to a second, different from the first operating state the operating state of the integrated circuit. For this purpose, the output signal produced will be overwritten from the outside on a circuit output. The inventive method and the integrated circuit according to the invention have the advantage that the switching from one operating state to another operating state of the integrated circuit can be performed in a very simple manner, but with high noise immunity. If necessary, the switch can easily be introduced, because it requires only the application of a voltage level is necessary at an output of the integrated circuit, which is already available in the system. It is also ensured by the choice of a circuit output, the switchover no accident occurs with high security, because it is largely excluded by the usual external wiring of a circuit output.
