    ==============================================================================
      [..]
      The common HAL driver contains a set of generic and common APIs that can be
      used by the PPP peripheral drivers and the user to start using the HAL.
      [..]
      The HAL contains two APIs' categories:
           (+) Common HAL APIs
           (+) Services HAL APIs

                ##### Initialization and de-initialization functions #####
   ===============================================================================
      [..]  This section provides functions allowing to:
        (+) Initialize the Flash interface the NVIC allocation and initial time base
            clock configuration.
        (+) De-initialize common part of the HAL.
        (+) Configure the time base source to have 1ms time base with a dedicated
            Tick interrupt priority.
          (++) SysTick timer is used by default as source of time base, but user
               can eventually implement his proper time base source (a general purpose
               timer for example or other time source), keeping in mind that Time base
               duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
               handled in milliseconds basis.
          (++) Time base configuration function (HAL_InitTick ()) is called automatically
               at the beginning of the program after reset by HAL_Init() or at any time
               when clock is configured, by HAL_RCC_ClockConfig().
          (++) Source of time base is configured  to generate interrupts at regular
               time intervals. Care must be taken if HAL_Delay() is called from a
               peripheral ISR process, the Tick interrupt line must have higher priority
              (numerically lower) than the peripheral interrupt. Otherwise the caller
              ISR process will be blocked.
         (++) functions affecting time base configurations are declared as __weak
               to make  override possible  in case of other  implementations in user file.
