Abstract:
Method for controlling an electronic device which has at least two modules (7,8) which are connected to one another via an optical bus (4), the method comprising the steps of:in an energy-saving mode, each of the modules (7,8) is switched to receive with a sampling period (P) which is the same for all modules (7,8), and for a sampling time interval (T) which is short in comparison with the sampling period (P),one of these modules (7,8) sends an interrupt signal (I) to the optical bus (4), whose duration is equal to or longer than the sampling period (P), andwhen an interrupt signal (I) is received, at least one other of these modules (7,8) is switched to permanent receive in the next sampling time interval (T) wherein the module (8) which sends the interrupt signal (I) is switched to permanent receive when the interrupt signal (I) is sent.
