1. The Low power wait mode is entered when executing a WFE instruction in Low power run mode. In WFE mode, the
interrupt is served if it has been previously enabled. After processing the interrupt, the processor goes back to WFE mode.
When the interrupt is configured as a wakeup event, the CPU wakes up and resumes processing.
2. 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 STM8L051/L052 Value Line,
STM8L151/L152, STM8L162, STM8AL31, STM8AL3L MCU lines reference manual (RM0031).
3. The device is woken up from Halt or Active-halt mode only when the address received matches the interface address.
