Detailed Description

Initialization and de-initialization functions.

 ===============================================================================
             ##### Initialization and de-initialization functions  #####
 ===============================================================================
    [..]
    This section provides functions allowing to initialize the DMA Stream source
    and destination addresses, incrementation and data sizes, transfer direction, 
    circular/normal mode selection, memory-to-memory mode selection and Stream priority value.
    [..]
    The HAL_DMA_Init() function follows the DMA configuration procedures as described in
    reference manual.
