241         (++) WFI entry mode, Any peripheral interrupt acknowledged by the nested vectored interrupt
242              controller (NVIC) can wake up the device from Sleep mode.
243         (++) WFE entry mode, Any wakeup event can wake up the device from Sleep mode.
245            (+++) Any EXTI Line (Internal or External) configured in Event mode
247    *** Stop mode ***
250       The Stop mode is based on the Cortex-M3 deepsleep mode combined with peripheral
251       clock gating. The voltage regulator can be configured either in normal or low-power mode.
252       In Stop mode, all clocks in the 1.8 V domain are stopped, the PLL, the HSI and the HSE RC
254       In Stop mode, all I/O pins keep the same state as in Run mode.
257 … The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_REGULATOR_VALUE, PWR_SLEEPENTRY_WFx )

265           (++) WFE entry mode, Any EXTI Line (Internal or External) configured in Event mode.
267    *** Standby mode ***
270       The Standby mode allows to achieve the lowest power consumption. It is based on the
271       Cortex-M3 deepsleep mode, with the voltage regulator disabled. The 1.8 V domain is
277         (++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
282    *** Auto-wakeup (AWU) from low-power mode ***
286        (+) The MCU can be woken up from low-power mode by an RTC Alarm event,
287            without depending on an external interrupt (Auto-wakeup mode).
