Beschreibung
Zusammenfassung:	Created by a passive resistor (W1,W2), a potential value at a signal output (OUT) causes a switchover into a test mode when a test signal (SW1,SW2) is coupled to the signal output and a circuit device (SCH) generates test signals by applying defined potential values. In a first preset time period the potential at the signal output is compared with preset reference values. In a second time period the integrated circuit (IC) is switched over into a test mode. An Independent claim is also included for a circuit structure for switching over the method of the present invention into a test mode.
