-  * @brief   DMA Extension HAL module driver
-  *         This file provides firmware functions to manage the following 
-  *         functionalities of the DMA Extension peripheral:
-  *           + Extended features functions
-  *

-  ==============================================================================
-                        ##### How to use this driver #####
-  ==============================================================================
-  [..]
-  The DMA Extension HAL driver can be used as follows:
-   (#) Start a multi buffer transfer using the HAL_DMA_MultiBufferStart() function
-       for polling mode or HAL_DMA_MultiBufferStart_IT() for interrupt mode.
-                   
-     -@-  In Memory-to-Memory transfer mode, Multi (Double) Buffer mode is not allowed.
-     -@-  When Multi (Double) Buffer mode is enabled the, transfer is circular by default.
-     -@-  In Multi (Double) buffer mode, it is possible to update the base address for 
-          the AHB memory port on the fly (DMA_SxM0AR or DMA_SxM1AR) when the stream is enabled.
