Data Structures
struct	MMCSD_Params
	MMCSD instance attributes - used during initialization. More...
struct	MMCSD_Attrs
	MMCSD instance attributes - used during init time. More...

Macros
MACROS used to select the transfer mode
MMCSD_MODE_BLOCKING block task execution while a Transfer is in progress MMCSD_MODE_CALLBACK does not block task execution; but calls a callback function when the MMCSD transfer has completed
#define	MMCSD_MODE_BLOCKING   ((uint32_t) 0U)
#define	MMCSD_MODE_CALLBACK   ((uint32_t) 1U)
