Abstract: An integrated circuit device having a processing unit (3) with a plurality of input terminals (I1-In) and adapted to cancel its stand-by mode when a pulse-like control signal (A) having a predetermined duration is received by one of the input terminals. The integrated circuit device includes a plurality of external terminals (T1-Tn) for receiving signals and a plurality of control signal generating circuits (C1-Cn) each having an input connected to a corresponding one of the external terminals. Each control signal generating circuit (C1-Cn) has an output terminal connected to a corresponding one of the input terminals of the processing unit (3). Each of the control signal generating circuits has a D flip-flop (4) for, on receiving a pulse signal (R) for canceling the stand-by mode from the processing unit (3), elongating a duration of the pulse signal to a predetermined duration.
