  ==============================================================================
                     ##### How to use this driver #####
  ==============================================================================
    [..]
      The LPTIM HAL driver can be used as follows:

      (#)Initialize the LPTIM low level resources by implementing the
        HAL_LPTIM_MspInit():
         (++) Enable the LPTIM interface clock using __HAL_RCC_LPTIMx_CLK_ENABLE().
         (++) In case of using interrupts (e.g. HAL_LPTIM_PWM_Start_IT()):
             (+++) Configure the LPTIM interrupt priority using HAL_NVIC_SetPriority().
             (+++) Enable the LPTIM IRQ handler using HAL_NVIC_EnableIRQ().
             (+++) In LPTIM IRQ handler, call HAL_LPTIM_IRQHandler().

      (#)Initialize the LPTIM HAL using HAL_LPTIM_Init(). This function
         configures mainly:
         (++) The instance: LPTIM1 or LPTIM2.
         (++) Clock: the counter clock.
             (+++) Source   : it can be either the ULPTIM input (IN1) or one of
                              the internal clock; (APB, LSE, LSI or HSI).
             (+++) Prescaler: select the clock divider.
      (#)Six modes are available:

         (++) PWM Mode: To generate a PWM signal with specified period and pulse,
         call HAL_LPTIM_PWM_Start() or HAL_LPTIM_PWM_Start_IT() for interruption
         mode.

         (++) One Pulse Mode: To generate pulse with specified width in response
         to a stimulus, call HAL_LPTIM_OnePulse_Start() or
         HAL_LPTIM_OnePulse_Start_IT() for interruption mode.

         (++) Set once Mode: In this mode, the output changes the level (from
         low level to high level if the output polarity is configured high, else
         the opposite) when a compare match occurs. To start this mode, call
         HAL_LPTIM_SetOnce_Start() or HAL_LPTIM_SetOnce_Start_IT() for
         interruption mode.

         (++) Encoder Mode: To use the encoder interface call
         HAL_LPTIM_Encoder_Start() or HAL_LPTIM_Encoder_Start_IT() for
         interruption mode. Only available for LPTIM1 instance.

         (++) Time out Mode: an active edge on one selected trigger input rests
         the counter. The first trigger event will start the timer, any
         successive trigger event will reset the counter and the timer will
         restart. To start this mode call HAL_LPTIM_TimeOut_Start_IT() or
         HAL_LPTIM_TimeOut_Start_IT() for interruption mode.

         (++) Counter Mode: counter can be used to count external events on
         the LPTIM Input1 or it can be used to count internal clock cycles.
         To start this mode, call HAL_LPTIM_Counter_Start() or
         HAL_LPTIM_Counter_Start_IT() for interruption mode.


      (#) User can stop any process by calling the corresponding API:
          HAL_LPTIM_Xxx_Stop() or HAL_LPTIM_Xxx_Stop_IT() if the process is
          already started in interruption mode.

      (#) De-initialize the LPTIM peripheral using HAL_LPTIM_DeInit().

    *** Callback registration ***
  =============================================
  [..]
  The compilation define  USE_HAL_LPTIM_REGISTER_CALLBACKS when set to 1
  allows the user to configure dynamically the driver callbacks.
  [..]
  Use Function @ref HAL_LPTIM_RegisterCallback() to register a callback.
  @ref HAL_LPTIM_RegisterCallback() takes as parameters the HAL peripheral handle,
  the Callback ID and a pointer to the user callback function.
  [..]
  Use function @ref HAL_LPTIM_UnRegisterCallback() to reset a callback to the
  default weak function.
  @ref HAL_LPTIM_UnRegisterCallback takes as parameters the HAL peripheral handle,
  and the Callback ID.
  [..]
  These functions allow to register/unregister following callbacks:

    (+) MspInitCallback         : LPTIM Base Msp Init Callback.
    (+) MspDeInitCallback       : LPTIM Base Msp DeInit Callback.
    (+) CompareMatchCallback    : Compare match Callback.
    (+) AutoReloadMatchCallback : Auto-reload match Callback.
    (+) TriggerCallback         : External trigger event detection Callback.
    (+) CompareWriteCallback    : Compare register write complete Callback.
    (+) AutoReloadWriteCallback : Auto-reload register write complete Callback.
    (+) DirectionUpCallback     : Up-counting direction change Callback.
    (+) DirectionDownCallback   : Down-counting direction change Callback.

  [..]
  By default, after the Init and when the state is HAL_LPTIM_STATE_RESET
  all interrupt callbacks are set to the corresponding weak functions:
  examples @ref HAL_LPTIM_TriggerCallback(), @ref HAL_LPTIM_CompareMatchCallback().

  [..]
  Exception done for MspInit and MspDeInit functions that are reset to the legacy weak
  functionalities in the Init/DeInit only when these callbacks are null
  (not registered beforehand). If not, MspInit or MspDeInit are not null, the Init/DeInit
  keep and use the user MspInit/MspDeInit callbacks (registered beforehand)

  [..]
  Callbacks can be registered/unregistered in HAL_LPTIM_STATE_READY state only.
  Exception done MspInit/MspDeInit that can be registered/unregistered
  in HAL_LPTIM_STATE_READY or HAL_LPTIM_STATE_RESET state,
  thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
  In that case first register the MspInit/MspDeInit user callbacks
  using @ref HAL_LPTIM_RegisterCallback() before calling DeInit or Init function.

  [..]
  When The compilation define USE_HAL_LPTIM_REGISTER_CALLBACKS is set to 0 or
  not defined, the callback registration feature is not available and all callbacks
  are set to the corresponding weak functions.
