@verbatim
 ===============================================================================
                 ##### Peripheral Control functions #####
 ===============================================================================
     
    *** PVD configuration ***
    =========================
    [..]
      (+) The PVD is used to monitor the VDD power supply by comparing it to a
          threshold selected by the PVD Level (PLS[2:0] bits in the PWR_CR).

      (+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
          than the PVD threshold. This event is internally connected to the EXTI
          line16 and can generate an interrupt if enabled. This is done through
          __HAL_PVD_EXTI_ENABLE_IT() macro.
      (+) The PVD is stopped in Standby mode.

    *** WakeUp pin configuration ***
    ================================
    [..]
      (+) WakeUp pin is used to wake up the system from Standby mode. This pin is
          forced in input pull-down configuration and is active on rising edges.
      (+) There is one WakeUp pin:
          WakeUp Pin 1 on PA.00.

    [..]

    *** Low Power modes configuration ***
    =====================================
     [..]
      The device features 3 low-power modes:
      (+) Sleep mode: CPU clock off, all peripherals including Cortex-M3 core peripherals like 
                      NVIC, SysTick, etc. are kept running
      (+) Stop mode: All clocks are stopped
      (+) Standby mode: 1.8V domain powered off
  
  
   *** Sleep mode ***
   ==================
    [..]
      (+) Entry:
          The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFx)
              functions with
          (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
          (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
     
      (+) Exit:
        (++) WFI entry mode, Any peripheral interrupt acknowledged by the nested vectored interrupt
             controller (NVIC) can wake up the device from Sleep mode.
        (++) WFE entry mode, Any wakeup event can wake up the device from Sleep mode.
           (+++) Any peripheral interrupt w/o NVIC configuration & SEVONPEND bit set in the Cortex (HAL_PWR_EnableSEVOnPend)
           (+++) Any EXTI Line (Internal or External) configured in Event mode

   *** Stop mode ***
   =================
    [..]
      The Stop mode is based on the Cortex-M3 deepsleep mode combined with peripheral
      clock gating. The voltage regulator can be configured either in normal or low-power mode.
      In Stop mode, all clocks in the 1.8 V domain are stopped, the PLL, the HSI and the HSE RC 
      oscillators are disabled. SRAM and register contents are preserved.
      In Stop mode, all I/O pins keep the same state as in Run mode.

      (+) Entry:
           The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_REGULATOR_VALUE, PWR_SLEEPENTRY_WFx )
             function with:
          (++) PWR_REGULATOR_VALUE= PWR_MAINREGULATOR_ON: Main regulator ON.
          (++) PWR_REGULATOR_VALUE= PWR_LOWPOWERREGULATOR_ON: Low Power regulator ON.
          (++) PWR_SLEEPENTRY_WFx= PWR_SLEEPENTRY_WFI: enter STOP mode with WFI instruction
          (++) PWR_SLEEPENTRY_WFx= PWR_SLEEPENTRY_WFE: enter STOP mode with WFE instruction
      (+) Exit:
          (++) WFI entry mode, Any EXTI Line (Internal or External) configured in Interrupt mode with NVIC configured
          (++) WFE entry mode, Any EXTI Line (Internal or External) configured in Event mode.

   *** Standby mode ***
   ====================
     [..]
      The Standby mode allows to achieve the lowest power consumption. It is based on the
      Cortex-M3 deepsleep mode, with the voltage regulator disabled. The 1.8 V domain is 
      consequently powered off. The PLL, the HSI oscillator and the HSE oscillator are also 
      switched off. SRAM and register contents are lost except for registers in the Backup domain 
      and Standby circuitry
      
      (+) Entry:
        (++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
      (+) Exit:
        (++) WKUP pin rising edge, RTC alarm event rising edge, external Reset in 
             NRSTpin, IWDG Reset

   *** Auto-wakeup (AWU) from low-power mode ***
       =============================================
       [..]
        
       (+) The MCU can be woken up from low-power mode by an RTC Alarm event, 
           without depending on an external interrupt (Auto-wakeup mode).
   
       (+) RTC auto-wakeup (AWU) from the Stop and Standby modes

           (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to 
                configure the RTC to generate the RTC alarm using the HAL_RTC_SetAlarm_IT() function.

   *** PWR Workarounds linked to Silicon Limitation ***
       ====================================================
       [..]
       Below the list of all silicon limitations known on STM32F1xx prouct.

       (#)Workarounds Implemented inside PWR HAL Driver
