1. The Low power wait mode is entered when executing a WFE instruction in Low power run mode.
2. In WFE mode, this interrupt is served if it has been previously enabled. After processing the interrupt, the processor goes
back to WFE mode. When this interrupt is configured as a wakeup event, the CPU wakes up and resumes processing.
3. The interrupt from PVD is logically OR-ed with Port E and F interrupts. Register EXTI_CONF allows to select between Port
E and Port F interrupt (see External interrupt port select register (EXTI_CONF) in the RM0031).
4. The device is woken up from Halt or Active-halt mode only when the address received matches the interface address.
