ABSTRACT:
Apparatus for controlling an integrated circuit comprises a power control device for controlling the power to at least part of the integrated circuit, the power control device is connected to a first input, for receiving a power-down signal, and a second input, for receiving a power-up signal, the power control device is adapted to power-up the at least part of the integrated circuit if a power-up signal is received at the second input when the at least part of the integrated circuit is in a powered-down state, and the power control device is further adapted to maintain the at least part of the integrated circuit in the powered-up state regardless of any signal received at the second input when the at least part of the integrated circuit is in a powered-up state, the apparatus is arranged so that the second input is also connected to a component of the integrated circuit and the apparatus comprising means for sending a signal to the component of the integrated circuit via the second input when the at least part of the integrated circuit is in the powered-up state.
