A system (10) comprises an electronic device (16) including at least one input (32) for receiving at least one enable signal and external data. The system (10) also comprises a wake-up circuit (18) including at least one input (28) for receiving at least one informational signal, an output (34) for sending the at least one enable signal to the electronic device (16), and a data interface for external configuration of the wake-up circuit (18). If the at least one informational signal satisfies predefined criteria, the wake-up circuit (18) enables the electronic device (16) by way of the at least one enable signal before the external data is received by the electronic device (16).
