Functions
HAL_StatusTypeDef	HAL_MMCEx_ConfigDMAMultiBuffer (MMC_HandleTypeDef hmmc, uint32_t pDataBuffer0, uint32_t *pDataBuffer1, uint32_t BufferSize)
	Configure DMA Dual Buffer mode. The Data transfer is managed by an Internal DMA. More...

HAL_StatusTypeDef	HAL_MMCEx_ReadBlocksDMAMultiBuffer (MMC_HandleTypeDef *hmmc, uint32_t BlockAdd, uint32_t NumberOfBlocks)
	Reads block(s) from a specified address in a card. The received Data will be stored in Buffer0 and Buffer1. Buffer0, Buffer1 and BufferSize need to be configured by function HAL_MMCEx_ConfigDMAMultiBuffer before call this function. More...

HAL_StatusTypeDef	HAL_MMCEx_WriteBlocksDMAMultiBuffer (MMC_HandleTypeDef *hmmc, uint32_t BlockAdd, uint32_t NumberOfBlocks)
	Write block(s) to a specified address in a card. The transfered Data are stored in Buffer0 and Buffer1. Buffer0, Buffer1 and BufferSize need to be configured by function HAL_MMCEx_ConfigDMAMultiBuffer before call this function. More...

HAL_StatusTypeDef	HAL_MMCEx_ChangeDMABuffer (MMC_HandleTypeDef hmmc, HAL_MMCEx_DMABuffer_MemoryTypeDef Buffer, uint32_t pDataBuffer)
	Change the DMA Buffer0 or Buffer1 address on the fly. More...

__weak void	HAL_MMCEx_Read_DMADoubleBuffer0CpltCallback (MMC_HandleTypeDef *hmmc)
	Read DMA Buffer 0 Transfer completed callbacks. More...

__weak void	HAL_MMCEx_Read_DMADoubleBuffer1CpltCallback (MMC_HandleTypeDef *hmmc)
	Read DMA Buffer 1 Transfer completed callbacks. More...

__weak void	HAL_MMCEx_Write_DMADoubleBuffer0CpltCallback (MMC_HandleTypeDef *hmmc)
	Write DMA Buffer 0 Transfer completed callbacks. More...

__weak void	HAL_MMCEx_Write_DMADoubleBuffer1CpltCallback (MMC_HandleTypeDef *hmmc)
	Write DMA Buffer 1 Transfer completed callbacks. More...

==============================================================================
[..]
 The MMC Extension HAL driver can be used as follows:
 (+) Configure Buffer0 and Buffer1 start address and Buffer size using HAL_MMCEx_ConfigDMAMultiBuffer() function.

 (+) Start Read and Write for multibuffer mode using HAL_MMCEx_ReadBlocksDMAMultiBuffer() and HAL_MMCEx_WriteBlocksDMAMultiBuffer() functions.
