SD/MMC memory APIs required by CTRL_ACCESS module (Memory Control Access).
For usual application which use the SD/MMC card in memory mode through a file system or a USB device MSC, only a call of sd_mmc_init() function is required in the startup.

This command may be used to check the media status of LUNs with removable media.
