  ==============================================================================
                        ##### How to use this driver #####
  ==============================================================================
  [..]
   (#) Enable and latch error information through HAL_RAMECC_Init().

   (#) For a given Monitor, enable and disable interrupt through
       HAL_RAMECC_EnableNotification().
       To enable a notification for a given RAMECC instance, use global
       interrupts.
       To enable a notification for only RAMECC monitor, use monitor interrupts.
       All possible notifications are defined in the driver header file under
       RAMECC_Interrupt group.

     *** Silent mode ***
     ===================
    [..]
          (+) Use HAL_RAMECC_StartMonitor() to start RAMECC latch failing
              information without enabling any notification.

     *** Interrupt mode ***
     ======================
    [..]
          (+) Use HAL_RAMECC_EnableNotification() to enable interrupts for a
              given error.
          (+) Configure the RAMECC interrupt priority using
              HAL_NVIC_SetPriority().
          (+) Enable the RAMECC IRQ handler using HAL_NVIC_EnableIRQ().
          (+) Start RAMECC latch failing information using HAL_RAMECC_StartMonitor().

     *** Failing information ***
     ======================
    [..]
     (#) Use HAL_RAMECC_GetFailingAddress() function to return the RAMECC
         failing address.
     (#) Use HAL_RAMECC_GetFailingDataLow() function to return the RAMECC
         failing data low.
     (#) Use HAL_RAMECC_GetFailingDataHigh() function to return the RAMECC
         failing data high.
     (#) Use HAL_RAMECC_GetHammingErrorCode() function to return the RAMECC
         Hamming bits injected.
     (#) Use HAL_RAMECC_IsECCSingleErrorDetected() function to check if a single
         error was detected and corrected.
     (#) Use HAL_RAMECC_IsECCDoubleErrorDetected() function to check if a double
         error was dedetected.

     *** RAMECC HAL driver macros list ***
     =============================================
     [..]
       Below the list of used macros in RAMECC HAL driver.

      (+) __HAL_RAMECC_ENABLE_IT  : Enable the specified ECCRAM Monitor
                                    interrupts.
      (+) __HAL_RAMECC_DISABLE_IT : Disable the specified ECCRAM Monitor
                                    interrupts.
      (+) __HAL_RAMECC_GET_FLAG   : Return the current RAMECC Monitor selected
                                    flag.
      (+) __HAL_RAMECC_CLEAR_FLAG : Clear the current RAMECC Monitor selected
                                    flag.

    ##### Callback registration #####
    ==================================
    [..]
      (#) The compilation define USE_HAL_RAMECC_REGISTER_CALLBACKS when set to 1
          allows the user to configure dynamically the driver callback.

    [..]
      (#) Use Function HAL_RAMECC_RegisterCallback() to register a user callback.
      (#) Function HAL_RAMECC_RegisterCallback() allows to register following callback:
         (+) RAMECCErrorCode        : RAMECC error code detection.
      (#) This function takes as parameters the HAL peripheral handle 
          and a pointer to the user callback function.

    [..]
      (#) Use function HAL_RAMECC_UnRegisterCallback() to reset a callback to the default
          weak function.
      (#) HAL_RAMECC_UnRegisterCallback() takes as parameters the HAL peripheral handle.
      (#) This function allows to reset following callback:
          (+) RAMECCErrorCode        : RAMECC error code detection.
    [..]
      (#) When The compilation define USE_HAL_RAMECC_REGISTER_CALLBACKS is set to 0 or
          not defined, the callback registration feature is not available
          and weak callbacks are used.
