Enumerations
enum	MMCSD_TransStatus { MMCSD_TRANS_SUCCESS = 0U, MMCSD_TRANS_FAILURE = 1U, MMCSD_TRANS_IRRECOVERABLE = 2U }

Functions
void	MMCSD_init (void)
	This function initializes the MMCSD module. More...

void	MMCSD_deinit (void)
	This function de-initializes the MMCSD module. More...

void	MMCSD_Params_init (MMCSD_Params *mmcsdParams)
	Initialize data structure with defaults. More...

MMCSD_Handle	MMCSD_open (uint32_t index, const MMCSD_Params *openParams)
	This function opens a given MMCSD peripheral. More...

void	MMCSD_close (MMCSD_Handle handle)
	Function to close a MMCSD peripheral specified by the MMCSD handle. More...

MMCSD_Handle	MMCSD_getHandle (uint32_t index)
	This function returns the handle of an open MMCSD Instance from the instance index. More...

int32_t	MMCSD_read (MMCSD_Handle handle, uint8_t *buf, uint32_t startBlk, uint32_t numBlks)
	Function to perform block reads from the MMC/SD media. More...

int32_t	MMCSD_write (MMCSD_Handle handle, uint8_t *buf, uint32_t startBlk, uint32_t numBlks)
	Function to perform block writes to the MMC/SD media. More...

uint32_t	MMCSD_getBlockSize (MMCSD_Handle handle)
	This function returns the block size of the MMC/SD media connected to the MMCSD controller. More...

uint32_t	MMCSD_getBlockCount (MMCSD_Handle handle)
	This function returns the block count of User Data Area of the MMC/SD media connected to the MMCSD controller. More...

uint32_t	MMCSD_isHC (MMCSD_Handle handle)
	This function returns if the media connected is High Capacity (> 2GB in size) or not. More...

int32_t	MMCSD_enableBootPartition (MMCSD_Handle handle, uint32_t partitionNum)
	This function enables the boot partition and gives access to the partition if the connected media is eMMC. This function essentially calls MMCSD_setEcsdBootPartitionEnable and MMCSD_enablePartitionAccess and is there to keep backward compatibility. More...

int32_t	MMCSD_setEcsdBootPartitionEnable (MMCSD_Handle handle, uint32_t partitionNum)
	This function enables the boot partition in the ECSD if the connected media is eMMC. More...

int32_t	MMCSD_enablePartitionAccess (MMCSD_Handle handle, uint32_t partitionNum)
	This function gives access to the partition if the connected media is eMMC. More...

int32_t	MMCSD_disableBootPartition (MMCSD_Handle handle)
	This function disables the boot partition if the connected media is eMMC. More...

uint32_t	MMCSD_getInputClk (MMCSD_Handle handle)
	This function returns the input clk frequency MMCSD was programmed at. More...

Variables
MMCSD_Config	gMmcsdConfig []
	Externally defined driver configuration array. More...

uint32_t	gMmcsdConfigNum
	Externally defined driver configuration array size. More...
