Very low power real time clock
摘要：
A very low power real-time clock is provided. The real-time clock includes a real-time clock core and a real-time clock controller, both included in an electronic device. The core is powered both when the electronic device is powered on and when it is powered off. When the electronic device is powered off, the core operates on battery power. The controller is powered off when the electronic device is powered off, to save power. The core maintains a tick count and a seconds count. Because the core is powered on even when the electronic device is powered off, the core continues to update the tick count and seconds count even when the electronic device is powered off. The controller provides access, to external components, to the core. By not powering the controller when the electronic device is powered off, non-core functions do not draw power from a battery.
摘要（中）：

提供了一个非常低功耗的实时时钟。 实时时钟包括实时时钟核心和实时时钟控制器，均包含在电子设备中。 当电子设备上电时和断电时，内核都将通电。 当电子设备关闭电源时，内核将以电池供电。 当电子设备关闭电源时，控制器关闭电源，以节省电力。 核心保持滴答计数和秒计数。 因为即使电子设备关闭电源，核心仍然通电，即使电子设备断电，核心也会继续更新刻度计数和秒计数。 控制器提供对外部组件到核心的访问。 当电子设备断电时，不对控制器供电，非核心功能不会从电池中吸取电力。
