25   [..]
26    The SD Extension HAL driver can be used as follows:
27    (+) Configure Buffer0 and Buffer1 start address and Buffer size using HAL_SDEx_ConfigDMAMultiBuffer() function.
28    (+) Start Read and Write for multibuffer mode using HAL_SDEx_ReadBlocksDMAMultiBuffer()
29        and HAL_SDEx_WriteBlocksDMAMultiBuffer() functions.
