  ==============================================================================
                        ##### How to use this driver #####
  ==============================================================================
  [..]
   (#) Enable and configure the peripheral to be connected to the DMA Channel
       (except for internal SRAM / FLASH memories: no initialization is
       necessary). Please refer to the Reference manual for connection between peripherals
       and DMA requests.

   (#) For a given Channel, program the required configuration through the following parameters:
       Channel request, Transfer Direction, Source and Destination data formats,
       Circular or Normal mode, Channel Priority level, Source and Destination Increment mode
       using HAL_DMA_Init() function.

       Prior to HAL_DMA_Init the peripheral clock shall be enabled for both DMA & DMAMUX
       thanks to:
      (##) DMA1 or DMA2: __HAL_RCC_DMA1_CLK_ENABLE() or  __HAL_RCC_DMA2_CLK_ENABLE() ;
      (##) DMAMUX1:      __HAL_RCC_DMAMUX1_CLK_ENABLE();

   (#) Use HAL_DMA_GetState() function to return the DMA state and HAL_DMA_GetError() in case of error
       detection.

   (#) Use HAL_DMA_Abort() function to abort the current transfer

     -@-   In Memory-to-Memory transfer mode, Circular mode is not allowed.

     *** Polling mode IO operation ***
     =================================
     [..]
       (+) Use HAL_DMA_Start() to start DMA transfer after the configuration of Source
           address and destination address and the Length of data to be transferred
       (+) Use HAL_DMA_PollForTransfer() to poll for the end of current transfer, in this
           case a fixed Timeout can be configured by User depending from his application.

     *** Interrupt mode IO operation ***
     ===================================
     [..]
       (+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority()
       (+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ()
       (+) Use HAL_DMA_Start_IT() to start DMA transfer after the configuration of
           Source address and destination address and the Length of data to be transferred.
           In this case the DMA interrupt is configured
       (+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() Interrupt subroutine
       (+) At the end of data transfer HAL_DMA_IRQHandler() function is executed and user can
              add his own function to register callbacks with HAL_DMA_RegisterCallback().

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

       (+) __HAL_DMA_ENABLE: Enable the specified DMA Channel.
       (+) __HAL_DMA_DISABLE: Disable the specified DMA Channel.
       (+) __HAL_DMA_GET_FLAG: Get the DMA Channel pending flags.
       (+) __HAL_DMA_CLEAR_FLAG: Clear the DMA Channel pending flags.
       (+) __HAL_DMA_ENABLE_IT: Enable the specified DMA Channel interrupts.
       (+) __HAL_DMA_DISABLE_IT: Disable the specified DMA Channel interrupts.
       (+) __HAL_DMA_GET_IT_SOURCE: Check whether the specified DMA Channel interrupt is enabled or not.

     [..]
      (@) You can refer to the DMA HAL driver header file for more useful macros
