+  * @brief   DMA Extension HAL module driver
+  *         This file provides firmware functions to manage the following

+  @verbatim
+  ==============================================================================
+                        ##### 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.
