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.
+ (+) Start Read and Write for multibuffer mode using HAL_SDEx_ReadBlocksDMAMultiBuffer()
+ and HAL_SDEx_WriteBlocksDMAMultiBuffer() functions.
