Abstract: A circuit assembly and a method for controlling operation states The circuit can be shifted by idle signals from the active operation state into the idle state and can be shifted by wake-up signals in an edge-triggered manner from the idle state into the active operation state if the wake-up signal executes a change in potential from a non-activation potential to an activation potential. The wake-up signals are supplied to a wake-up signal input of the circuit with the interposition of a masking circuit, which passes through the wake-up signals to the wake-up signal input in the idle state of the circuit and, in the active operation state of the circuit, applies to the wake-up signal input a predetermined electric masking potential, from which a change in potential towards the activation potential of the wake-up signal shifts the circuit from the idle state into the active operation state.
