Detailed Description

Interrupts and flags management functions.

            ##### Interrupts and flags management functions #####
 ===============================================================================

    [..] This section provides functions allowing to configure the DMA2D 
         Interrupts and to get the status and clear flags and Interrupts 
         pending bits.
    [..] The DMA2D provides 6 Interrupts sources and 6 Flags
