ABSTRACT:
A data processing apparatus having a dual rail circuit component and a control unit for production of drive signals for the dual rail circuit component. The control unit receives an operating mode selection signal, and drive signals for the connected dual rail circuit component are produced as a function of the operating mode selection signal. The circuit components are operated in a security mode or in a power saving mode as a function of the drive signals, with security measures being deactivated in the power saving mode.
