如果你希望他们在sleep模式下工作的话,必须单独配置。比如:
Bit 1 DMA2SMEN: DMA2 clocks enable during Sleep and Stop modes Set and cleared by software during Sleep mode.
0: DMA2 clocks disabled by the clock gating(1) during Sleep and Stop modes
1: DMA2 clocks enabled by the clock gating(1) during Sleep and Stop modes
TIMER也有类似配置。
