==============================================================================
                      ##### 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.
