Energiesparschaltung für ein elektronisches Gerät und Steuerverfahren zur Energieeinsparung in einem elektronischen Gerät

摘要

A communication control apparatus (108) for use in an electronic device (102) includes a device (111), first and second communication lines (116 and 117), and a controller (110). The device (111) and the controller (110) are interconnected by the first and second communication lines (116 and 117), which are driven by the controller (110). The first and second communication lines (116 and 117) have different capacities and the first communication line (116) is subject to disabling. The controller (110) programs the device (111) using the first communication line (116) prior to its disabling and programs the device (111) via the second communication line (117) while the first communication line (116) is disabled. The apparatus (108) permits periodic placement of portions of the electronic device (102), including a master clock (112), into a powered-off state from which return to a powered-on state is possible.
