23 ##### How to use this driver #####
24 ==============================================================================
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.
