Circuit arrangement and method for controlling a low power mode

For example, a circuit arrangement is provided, comprising: a clock generator which is adapted to generate a clock signal, a circuit with a low power mode and a control device which is adapted to perform: receiving, when the circuit is in the low power mode, a requirement which specifies that the circuit should return from the low power mode, and causing the circuit to return from the low power mode when the number of clock cycles of the clock signal has reached a threshold value since the receipt of the request.
