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 (uint32_t offset, uint8_t *buffer, uint16_t length)
	Reads raw data from the card.
uint8_t	sd_raw_read_interval (uint32_t offset, uint8_t *buffer, uint16_t interval, uint16_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 (uint32_t offset, const uint8_t *buffer, uint16_t length)
	Writes raw data to the card.
uint8_t	sd_raw_write_interval (uint32_t offset, uint8_t *buffer, uint16_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.
