pub unsafe fn sleep(cs: CriticalSection<'_>)Expand description
Sleep with WFI, attempting to enter the deepest STOP mode possible.
If it’s not possible to enter any STOP mode due to running peripherals it will
still do a WFI sleep. Therefore this function is equivalent to WFI except
with lower power consumption and higher latency.
§SAFETY
Care must be taken that we have ensured that the system is ready to go to deep sleep, otherwise HAL peripherals may misbehave. HAL drivers automatically prevent sleep as needed, but you might have to do it manually if you’re using some peripherals with the PAC directly.
