                        ##### How to use this driver #####
  ==============================================================================
  [..]
  The DMA Extension HAL driver can be used as follows:

   (+) Configure the DMA_MUX Synchronization Block using HAL_DMAEx_ConfigMuxSync function.
   (+) Configure the DMA_MUX Request Generator Block using HAL_DMAEx_ConfigMuxRequestGenerator function.
       Functions HAL_DMAEx_EnableMuxRequestGenerator and HAL_DMAEx_DisableMuxRequestGenerator can then be used
       to respectively enable/disable the request generator.

   (+) To handle the DMAMUX Interrupts, the function  HAL_DMAEx_MUX_IRQHandler should be called from
       the DMAMUX IRQ handler i.e DMAMUX1_OVR_IRQHandler.
       As only one interrupt line is available for all DMAMUX channels and request generators , HAL_DMAEx_MUX_IRQHandler should be
       called with, as parameter, the appropriate DMA handle as many as used DMAs in the user project
      (exception done if a given DMA is not using the DMAMUX SYNC block neither a request generator)
