低功耗定时可以运行在以LSE，LSI或外部时钟驱动的情况下，包括停止模式。
The low-power timer has an independentclock and is running also in Stop mode if it is clocked by LSE, LSI or anexternal clock.
外部设备——例如，通用串行总线(usb)端口或系统时钟。
External devices — For instance, Universal Serial Bus (USB) ports or the system clock.
CPU电源状态程度越深，采取的电能节省措施就越多 —比如说停止处理器时钟或停止外部中断请求。
The deeper the C state, the more power saving steps are taken—steps like stopping the processor clock or stopping interrupts from coming in.
许多时钟电路也与电阻器和电容器一起使用作为低成本的时间组分或驱动外部输入。
Many clock circuits also work with a resistor and capacitor as low-cost timing components or can be driven from an external source.
