 * @brief		Low level disk I/O module skeleton for FatFs
 * @note		If a working storage control module is available, it should
 *				be attached to the FatFs via a glue function rather than
 *				modifying it.\n
 *				This is an example of glue functions to attach various
 *				exsisting storage control module to the FatFs module with a
 *				defined API.
