Functions
uint32_t	SD_HighSpeed (SD_HandleTypeDef *hsd)
	Switches the SD card to High Speed mode. This API must be used after "Transfer State". More...

uint32_t	HAL_SDEx_HighSpeed (SD_HandleTypeDef *hsd)
	Switches the SD card to High Speed mode. This API must be used after "Transfer State". More...

void	HAL_SDEx_DriveTransceiver_1_8V_Callback (FlagStatus status)
	Enable/Disable the SD Transceiver 1.8V Mode Callback. More...

HAL_StatusTypeDef	HAL_SDEx_ConfigDMAMultiBuffer (SD_HandleTypeDef hsd, 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_SDEx_ReadBlocksDMAMultiBuffer (SD_HandleTypeDef *hsd, 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_SDEx_ConfigDMAMultiBuffer before call this function. More...

HAL_StatusTypeDef	HAL_SDEx_WriteBlocksDMAMultiBuffer (SD_HandleTypeDef *hsd, 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_SDEx_ConfigDMAMultiBuffer before call this function. More...

HAL_StatusTypeDef	HAL_SDEx_ChangeDMABuffer (SD_HandleTypeDef hsd, HAL_SDEx_DMABuffer_MemoryTypeDef Buffer, uint32_t pDataBuffer)
	Change the DMA Buffer0 or Buffer1 address on the fly. More...

void	HAL_SDEx_Read_DMADoubleBuffer0CpltCallback (SD_HandleTypeDef *hsd)
	Read DMA Buffer 0 Transfer completed callbacks. More...

void	HAL_SDEx_Read_DMADoubleBuffer1CpltCallback (SD_HandleTypeDef *hsd)
	Read DMA Buffer 1 Transfer completed callbacks. More...

void	HAL_SDEx_Write_DMADoubleBuffer0CpltCallback (SD_HandleTypeDef *hsd)
	Write DMA Buffer 0 Transfer completed callbacks. More...

void	HAL_SDEx_Write_DMADoubleBuffer1CpltCallback (SD_HandleTypeDef *hsd)
	Write DMA Buffer 1 Transfer completed callbacks. More...

                      ##### How to use this driver #####
==============================================================================
[..]
 The SD Extension HAL driver can be used as follows:
 (+) Set card in High Speed mode using HAL_SDEx_HighSpeed() function.
 (+) 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.
