Description: SD卡驱动
SD_CARD_TIMEOUT 当一个SD卡的操作超出时限，将导致返回错误和该标记被置位
SD_CARD_EXIST 当卡槽内插入了合适的卡体，不管是什么卡，都会使该位被设置；
SD_CARD_WRITE_PROTECT 当卡体的写保护开关被 LOCK 时，则该位被设置；
SD_CARD_READY 当卡槽内的卡被正确识别，并可以随时访问时，则该位被设置；
SD_CARD_DOOR_CLOSE 当卡槽的门（产品外壳上的挡板开关）关闭时，则该位被设置；
SD_CARD_IS_SD 当卡槽内插入的是 SD 卡时，则该位被设置。
SD_CARD_IS_MMC 当卡槽内插入的是 MMC 卡时，则该位被设置；
注意：不要使用 0x80，免得和整数作逻辑运算时被误为负数。
