  15.                         ##### How to use this driver #####
  16.   ==============================================================================
  17.   [..]
  18.     This driver implements a high level communication layer for read and write from/to
  19.     this memory. The needed STM32 hardware resources (SDMMC and GPIO) are performed by
  20.     the user in HAL_MMC_MspInit() function (MSP layer).
  21.     Basically, the MSP layer configuration should be the same as we provide in the
  22.     examples.
  23.     You can easily tailor this configuration according to hardware resources.
  24.  
  25.   [..]
  26.     This driver is a generic layered driver for SDMMC memories which uses the HAL
  27.     SDMMC driver functions to interface with MMC and eMMC cards devices.
  28.     It is used as follows:
  29.  
  30.     (#)Initialize the SDMMC low level resources by implement the HAL_MMC_MspInit() API:
  31.         (##) Enable the SDMMC interface clock using __HAL_RCC_SDMMC_CLK_ENABLE();
  32.         (##) SDMMC pins configuration for MMC card
  33.             (+++) Enable the clock for the SDMMC GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
  34.             (+++) Configure these SDMMC pins as alternate function pull-up using HAL_GPIO_Init()
  35.                   and according to your pin assignment;
  36.         (##) DMA Configuration if you need to use DMA process (HAL_MMC_ReadBlocks_DMA()
  37.              and HAL_MMC_WriteBlocks_DMA() APIs).
  38.             (+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE();
  39.             (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled.
  40.         (##) NVIC configuration if you need to use interrupt process when using DMA transfer.
  41.             (+++) Configure the SDMMC and DMA interrupt priorities using function HAL_NVIC_SetPriority();
  42.                   DMA priority is superior to SDMMC's priority
  43.             (+++) Enable the NVIC DMA and SDMMC IRQs using function HAL_NVIC_EnableIRQ()
  44.             (+++) SDMMC interrupts are managed using the macros __HAL_MMC_ENABLE_IT()
  45.                   and __HAL_MMC_DISABLE_IT() inside the communication process.
  46.             (+++) SDMMC interrupts pending bits are managed using the macros __HAL_MMC_GET_IT()
  47.                   and __HAL_MMC_CLEAR_IT()
  48.         (##) NVIC configuration if you need to use interrupt process (HAL_MMC_ReadBlocks_IT()
  49.              and HAL_MMC_WriteBlocks_IT() APIs).
  50.             (+++) Configure the SDMMC interrupt priorities using function HAL_NVIC_SetPriority();
  51.             (+++) Enable the NVIC SDMMC IRQs using function HAL_NVIC_EnableIRQ()
  52.             (+++) SDMMC interrupts are managed using the macros __HAL_MMC_ENABLE_IT()
  53.                   and __HAL_MMC_DISABLE_IT() inside the communication process.
  54.             (+++) SDMMC interrupts pending bits are managed using the macros __HAL_MMC_GET_IT()
  55.                   and __HAL_MMC_CLEAR_IT()
  56.     (#) At this stage, you can perform MMC read/write/erase operations after MMC card initialization
  57.  
  58.  
  59.   *** MMC Card Initialization and configuration ***
  60.   ================================================
  61.   [..]
  62.     To initialize the MMC Card, use the HAL_MMC_Init() function. It Initializes
  63.     SDMMC Peripheral (STM32 side) and the MMC Card, and put it into StandBy State (Ready for data transfer).
  64.     This function provide the following operations:
  65.  
  66.     (#) Initialize the SDMMC peripheral interface with defaullt configuration.
  67.         The initialization process is done at 400KHz. You can change or adapt
  68.         this frequency by adjusting the "ClockDiv" field.
  69.         The MMC Card frequency (SDMMC_CK) is computed as follows:
  70.  
  71.            SDMMC_CK = SDMMCCLK / (ClockDiv + 2)
  72.  
  73.         In initialization mode and according to the MMC Card standard,
  74.         make sure that the SDMMC_CK frequency doesn't exceed 400KHz.
  75.  
  76.         This phase of initialization is done through SDMMC_Init() and
  77.         SDMMC_PowerState_ON() SDMMC low level APIs.
  78.  
  79.     (#) Initialize the MMC card. The API used is HAL_MMC_InitCard().
  80.         This phase allows the card initialization and identification
  81.         and check the MMC Card type (Standard Capacity or High Capacity)
  82.         The initialization flow is compatible with MMC standard.
  83.  
  84.         This API (HAL_MMC_InitCard()) could be used also to reinitialize the card in case
  85.         of plug-off plug-in.
  86.  
  87.     (#) Configure the MMC Card Data transfer frequency. By Default, the card transfer
  88.         frequency is set to 24MHz. You can change or adapt this frequency by adjusting
  89.         the "ClockDiv" field.
  90.         In transfer mode and according to the MMC Card standard, make sure that the
  91.         SDMMC_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
  92.         To be able to use a frequency higher than 24MHz, you should use the SDMMC
  93.         peripheral in bypass mode. Refer to the corresponding reference manual
  94.         for more details.
  95.  
  96.     (#) Select the corresponding MMC Card according to the address read with the step 2.
  97.  
  98.     (#) Configure the MMC Card in wide bus mode: 4-bits data.
  99.

  106.         You can choose either one block read operation or multiple block read operation
  107.         by adjusting the "NumberOfBlocks" parameter.
  108.         After this, you have to ensure that the transfer is done correctly. The check is done
  109.         through HAL_MMC_GetCardState() function for MMC card state.
  110.  
  111.     (+) You can read from MMC card in DMA mode by using function HAL_MMC_ReadBlocks_DMA().

  188.  
  189.   [..]
  190.     (@) You can refer to the MMC HAL driver header file for more useful macros
  191.  
  192.   *** Callback registration ***
  193.   =============================================
  194.   [..]
  195.     The compilation define USE_HAL_MMC_REGISTER_CALLBACKS when set to 1
  196.     allows the user to configure dynamically the driver callbacks.
  197.  
  198.     Use Functions @ref HAL_MMC_RegisterCallback() to register a user callback,
  199.     it allows to register following callbacks:
  200.       (+) TxCpltCallback : callback when a transmission transfer is completed.
  201.       (+) RxCpltCallback : callback when a reception transfer is completed.
  202.       (+) ErrorCallback : callback when error occurs.
  203.       (+) AbortCpltCallback : callback when abort is completed.
  204.       (+) MspInitCallback    : MMC MspInit.
  205.       (+) MspDeInitCallback  : MMC MspDeInit.
  206.     This function takes as parameters the HAL peripheral handle, the Callback ID
  207.     and a pointer to the user callback function.
  208.  
  209.     Use function @ref HAL_MMC_UnRegisterCallback() to reset a callback to the default
  210.     weak (surcharged) function. It allows to reset following callbacks:
  211.       (+) TxCpltCallback : callback when a transmission transfer is completed.
  212.       (+) RxCpltCallback : callback when a reception transfer is completed.
  213.       (+) ErrorCallback : callback when error occurs.
  214.       (+) AbortCpltCallback : callback when abort is completed.
  215.       (+) MspInitCallback    : MMC MspInit.
  216.       (+) MspDeInitCallback  : MMC MspDeInit.
  217.     This function) takes as parameters the HAL peripheral handle and the Callback ID.
  218.  
  219.     By default, after the @ref HAL_MMC_Init and if the state is HAL_MMC_STATE_RESET
  220.     all callbacks are reset to the corresponding legacy weak (surcharged) functions.
  221.     Exception done for MspInit and MspDeInit callbacks that are respectively
  222.     reset to the legacy weak (surcharged) functions in the @ref HAL_MMC_Init
  223.     and @ref  HAL_MMC_DeInit only when these callbacks are null (not registered beforehand).
  224.     If not, MspInit or MspDeInit are not null, the @ref HAL_MMC_Init and @ref HAL_MMC_DeInit
  225.     keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
  226.  
  227.     Callbacks can be registered/unregistered in READY state only.
  228.     Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
  229.     in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
  230.     during the Init/DeInit.
  231.     In that case first register the MspInit/MspDeInit user callbacks
  232.     using @ref HAL_MMC_RegisterCallback before calling @ref HAL_MMC_DeInit
  233.     or @ref HAL_MMC_Init function.
  234.  
  235.     When The compilation define USE_HAL_MMC_REGISTER_CALLBACKS is set to 0 or
  236.     not defined, the callback registering feature is not available
  237.     and weak (surcharged) callbacks are used.
