+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ This driver implements a high level communication layer for read and write from/to
+ this memory. The needed STM32 hardware resources (SDMMC and GPIO) are performed by
+ the user in HAL_MMC_MspInit() function (MSP layer).
+ Basically, the MSP layer configuration should be the same as we provide in the
+ examples.
+ You can easily tailor this configuration according to hardware resources.
+
+ [..]
+ This driver is a generic layered driver for SDMMC memories which uses the HAL
+ SDMMC driver functions to interface with MMC and eMMC cards devices.
+ It is used as follows:
+
+ (#)Initialize the SDMMC low level resources by implement the HAL_MMC_MspInit() API:
+ (##) Enable the SDMMC interface clock using __HAL_RCC_SDMMC_CLK_ENABLE();
+ (##) SDMMC pins configuration for MMC card
+ (+++) Enable the clock for the SDMMC GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
+ (+++) Configure these SDMMC pins as alternate function pull-up using HAL_GPIO_Init()
+ and according to your pin assignment;
+ (##) NVIC configuration if you need to use interrupt process (HAL_MMC_ReadBlocks_IT()
+ and HAL_MMC_WriteBlocks_IT() APIs).
+ (+++) Configure the SDMMC interrupt priorities using function HAL_NVIC_SetPriority();
+ (+++) Enable the NVIC SDMMC IRQs using function HAL_NVIC_EnableIRQ()
+ (+++) SDMMC interrupts are managed using the macros __HAL_MMC_ENABLE_IT()
+ and __HAL_MMC_DISABLE_IT() inside the communication process.
+ (+++) SDMMC interrupts pending bits are managed using the macros __HAL_MMC_GET_IT()
+ and __HAL_MMC_CLEAR_IT()
+ (##) No general propose DMA Configuration is needed, an Internal DMA for SDMMC Peripheral are used.
+
+ (#) At this stage, you can perform MMC read/write/erase operations after MMC card initialization
+
+
+ *** MMC Card Initialization and configuration ***
+ ================================================
+ [..]
+ To initialize the MMC Card, use the HAL_MMC_Init() function. It Initializes
+ SDMMC Peripheral (STM32 side) and the MMC Card, and put it into StandBy State (Ready for data transfer).
+ This function provide the following operations:
+
+ (#) Initialize the SDMMC peripheral interface with default configuration.
+ The initialization process is done at 400KHz. You can change or adapt
+ this frequency by adjusting the "ClockDiv" field.
+ The MMC Card frequency (SDMMC_CK) is computed as follows:
+
+ SDMMC_CK = SDMMCCLK / (2 * ClockDiv)
+
+ In initialization mode and according to the MMC Card standard,
+ make sure that the SDMMC_CK frequency doesn't exceed 400KHz.
+
+ This phase of initialization is done through SDMMC_Init() and
+ SDMMC_PowerState_ON() SDMMC low level APIs.
+
+ (#) Initialize the MMC card. The API used is HAL_MMC_InitCard().
+ This phase allows the card initialization and identification
+ and check the MMC Card type (Standard Capacity or High Capacity)
+ The initialization flow is compatible with MMC standard.
+
+ This API (HAL_MMC_InitCard()) could be used also to reinitialize the card in case
+ of plug-off plug-in.
+
+ (#) Configure the MMC Card Data transfer frequency. By Default, the card transfer
+ frequency by adjusting the "ClockDiv" field.
+ In transfer mode and according to the MMC Card standard, make sure that the
+ SDMMC_CK frequency doesn't exceed 25MHz and 100MHz in High-speed mode switch.
+
+ (#) Select the corresponding MMC Card according to the address read with the step 2.
+
+ (#) Configure the MMC Card in wide bus mode: 4-bits data.
+
+ *** MMC Card Read operation ***
+ ==============================
+ [..]
+ (+) You can read from MMC card in polling mode by using function HAL_MMC_ReadBlocks().
+ This function support only 512-bytes block length (the block size should be
+ chosen as 512 bytes).
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_MMC_GetCardState() function for MMC card state.
+
+ (+) You can read from MMC card in DMA mode by using function HAL_MMC_ReadBlocks_DMA().
+ This function support only 512-bytes block length (the block size should be
+ chosen as 512 bytes).
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_MMC_GetCardState() function for MMC card state.
+ You could also check the DMA transfer process through the MMC Rx interrupt event.
+
+ (+) You can read from MMC card in Interrupt mode by using function HAL_MMC_ReadBlocks_IT().
+ This function allows the read of 512 bytes blocks.
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_MMC_GetCardState() function for MMC card state.
+ You could also check the IT transfer process through the MMC Rx interrupt event.
+
+ *** MMC Card Write operation ***
+ ===============================
+ [..]
+ (+) You can write to MMC card in polling mode by using function HAL_MMC_WriteBlocks().
+ This function support only 512-bytes block length (the block size should be
+ chosen as 512 bytes).
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_MMC_GetCardState() function for MMC card state.
+
+ (+) You can write to MMC card in DMA mode by using function HAL_MMC_WriteBlocks_DMA().
+ This function support only 512-bytes block length (the block size should be
+ chosen as 512 byte).
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_MMC_GetCardState() function for MMC card state.
+ You could also check the DMA transfer process through the MMC Tx interrupt event.
+
+ (+) You can write to MMC card in Interrupt mode by using function HAL_MMC_WriteBlocks_IT().
+ This function allows the read of 512 bytes blocks.
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_MMC_GetCardState() function for MMC card state.
+ You could also check the IT transfer process through the MMC Tx interrupt event.
+
+ *** MMC card information ***
+ ===========================
+ [..]
+ (+) To get MMC card information, you can use the function HAL_MMC_GetCardInfo().
+ It returns useful information about the MMC card such as block size, card type,
+ block number ...
+
+ *** MMC card CSD register ***
+ ============================
+ [..]
+ (+) The HAL_MMC_GetCardCSD() API allows to get the parameters of the CSD register.
+ Some of the CSD parameters are useful for card initialization and identification.
+
+ *** MMC card CID register ***
+ ============================
+ [..]
+ (+) The HAL_MMC_GetCardCID() API allows to get the parameters of the CID register.
+ Some of the CID parameters are useful for card initialization and identification.
+
+ *** MMC HAL driver macros list ***
+ ==================================
+ [..]
+ Below the list of most used macros in MMC HAL driver.
+
+ (+) __HAL_MMC_ENABLE_IT: Enable the MMC device interrupt
+ (+) __HAL_MMC_DISABLE_IT: Disable the MMC device interrupt
+ (+) __HAL_MMC_GET_FLAG:Check whether the specified MMC flag is set or not
+ (+) __HAL_MMC_CLEAR_FLAG: Clear the MMC's pending flags
+
+ [..]
+ (@) You can refer to the MMC HAL driver header file for more useful macros
+
+ *** Callback registration ***
+ =============================================
+ [..]
+ The compilation define USE_HAL_MMC_REGISTER_CALLBACKS when set to 1
+ allows the user to configure dynamically the driver callbacks.
+
+ Use Functions HAL_MMC_RegisterCallback() to register a user callback,
+ it allows to register following callbacks:
+ (+) TxCpltCallback : callback when a transmission transfer is completed.
+ (+) RxCpltCallback : callback when a reception transfer is completed.
+ (+) ErrorCallback : callback when error occurs.
+ (+) AbortCpltCallback : callback when abort is completed.
+ (+) Read_DMADblBuf0CpltCallback : callback when the DMA reception of first buffer is completed.
+ (+) Read_DMADblBuf1CpltCallback : callback when the DMA reception of second buffer is completed.
+ (+) Write_DMADblBuf0CpltCallback : callback when the DMA transmission of first buffer is completed.
+ (+) Write_DMADblBuf1CpltCallback : callback when the DMA transmission of second buffer is completed.
+ (+) MspInitCallback : MMC MspInit.
+ (+) MspDeInitCallback : MMC MspDeInit.
+ This function takes as parameters the HAL peripheral handle, the Callback ID
+ and a pointer to the user callback function.
+
+ Use function HAL_MMC_UnRegisterCallback() to reset a callback to the default
+ weak (surcharged) function. It allows to reset following callbacks:
+ (+) TxCpltCallback : callback when a transmission transfer is completed.
+ (+) RxCpltCallback : callback when a reception transfer is completed.
+ (+) ErrorCallback : callback when error occurs.
+ (+) AbortCpltCallback : callback when abort is completed.
+ (+) Read_DMADblBuf0CpltCallback : callback when the DMA reception of first buffer is completed.
+ (+) Read_DMADblBuf1CpltCallback : callback when the DMA reception of second buffer is completed.
+ (+) Write_DMADblBuf0CpltCallback : callback when the DMA transmission of first buffer is completed.
+ (+) Write_DMADblBuf1CpltCallback : callback when the DMA transmission of second buffer is completed.
+ (+) MspInitCallback : MMC MspInit.
+ (+) MspDeInitCallback : MMC MspDeInit.
+ This function) takes as parameters the HAL peripheral handle and the Callback ID.
+
+ By default, after the HAL_MMC_Init and if the state is HAL_MMC_STATE_RESET
+ all callbacks are reset to the corresponding legacy weak (surcharged) functions.
+ Exception done for MspInit and MspDeInit callbacks that are respectively
+ reset to the legacy weak (surcharged) functions in the HAL_MMC_Init
+ and HAL_MMC_DeInit only when these callbacks are null (not registered beforehand).
+ If not, MspInit or MspDeInit are not null, the HAL_MMC_Init and HAL_MMC_DeInit
+ keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
+
+ Callbacks can be registered/unregistered in READY state only.
+ Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
+ in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
+ during the Init/DeInit.
+ In that case first register the MspInit/MspDeInit user callbacks
+ using HAL_MMC_RegisterCallback before calling HAL_MMC_DeInit
+ or HAL_MMC_Init function.
+
+ When The compilation define USE_HAL_MMC_REGISTER_CALLBACKS is set to 0 or
+ not defined, the callback registering feature is not available
+ and weak (surcharged) callbacks are used.
