/**
 * \ingroup sdmmc_hal
 * \addtogroup mcid_module MCI Driver (HAL for SD/MMC Lib)
 *
 * \section Purpose
 *
 * This driver implements SD(IO)/MMC command operations and MCI configuration
 * routines to perform SD(IO)/MMC access. It's used for upper layer
 * (\ref libsdmmc_module "SD/MMC driver") to perform SD/MMC operations.
 *
 * \section Usage
 *
 * -# MCID_Init(): Initializes a MCI driver instance and the underlying
 *                 peripheral.
 * -# MCID_SendCmd(): Starts a MCI transfer which described by
 *                    \ref sSdmmcCommand.
 * -# MCID_CancelCmd(): Cancel a pending command.
 * -# MCID_IsCmdCompleted(): Check if MCI transfer is finished.
 * -# MCID_Handler(): Interrupt handler which is called by ISR handler.
 * -# MCID_IOCtrl(): IO control function to report HW attributes to upper
 *                   layer driver and modify HW settings (such as clock
 *                   frequency, High-speed support, etc. See
 *                   \ref sdmmc_ioctrls).
 *
 * \sa \ref dmad_module "DMA Driver", \ref hsmci_module "HSMCI",
 *     \ref libsdmmc_module "SD/MMC Library"
