SD/MMC/SDIO basic APIs used by SD/MMC/SDIO memory APIs (sd_mmc_stack_mem_group). Also, it can be used by application which use the SDIO card or specific application which does not need of File System.
For usual application which use the SD/MMC card in memory mode with a file system, please refer to sd_mmc_stack_mem_group.
