Data Structures
struct	sd_raw_info
	This struct is used by sd_raw_get_info() to return manufacturing and status information of the card. More...
Defines
#define	SD_RAW_FORMAT_HARDDISK
	The card's layout is harddisk-like, which means it contains a master boot record with a partition table.
#define	SD_RAW_FORMAT_SUPERFLOPPY
	The card contains a single filesystem and no partition table.
#define	SD_RAW_FORMAT_UNIVERSAL
	The card's layout follows the Universal File Format.
#define	SD_RAW_FORMAT_UNKNOWN
	The card's layout is unknown.
Functions
uint8_t	sd_raw_init ()
	Initializes memory card communication.
uint8_t	sd_raw_available ()
	Checks wether a memory card is located in the slot.
uint8_t	sd_raw_locked ()
	Checks wether the memory card is locked for write access.
uint8_t	sd_raw_read (offset_t offset, uint8_t *buffer, uintptr_t length)
	Reads raw data from the card.
uint8_t	sd_raw_read_interval (offset_t offset, uint8_t *buffer, uintptr_t interval, uintptr_t length, sd_raw_read_interval_handler_t callback, void *p)
	Continuously reads units of interval bytes and calls a callback function.
uint8_t	sd_raw_write (offset_t offset, const uint8_t *buffer, uintptr_t length)
	Writes raw data to the card.
uint8_t	sd_raw_write_interval (offset_t offset, uint8_t *buffer, uintptr_t length, sd_raw_write_interval_handler_t callback, void *p)
	Writes a continuous data stream obtained from a callback function.
uint8_t	sd_raw_sync ()
	Writes the write buffer's content to the card.
uint8_t	sd_raw_get_info (struct sd_raw_info *info)
	Reads informational data from the card.
