  ==============================================================================
  [..]
   The SD Extension HAL driver can be used as follows:
   (+) Configure Buffer0 and Buffer1 start address and Buffer size using HAL_SDEx_ConfigDMAMultiBuffer() function.
   (+) Start Read and Write for multibuffer mode using HAL_SDEx_ReadBlocksDMAMultiBuffer()
       and HAL_SDEx_WriteBlocksDMAMultiBuffer() functions.
