  18                        ##### SDMMC peripheral features #####
  19   ==============================================================================
  20     [..] The SD/SDMMC MMC card host interface (SDMMC) provides an interface between the APB2
  21          peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDMMC cards and CE-ATA
  22          devices.
  23
  24     [..] The SDMMC features include the following:
  25          (+) Full compliance with MultiMedia Card System Specification Version 4.2. Card support
  26              for three different databus modes: 1-bit (default), 4-bit and 8-bit
  27          (+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility)
  28          (+) Full compliance with SD Memory Card Specifications Version 2.0
  29          (+) Full compliance with SD I/O Card Specification Version 2.0: card support for two
  30              different data bus modes: 1-bit (default) and 4-bit
  31          (+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol
  32              Rev1.1)
  33          (+) Data transfer up to 48 MHz for the 8 bit mode
  34          (+) Data and command output enable signals to control external bidirectional drivers.
  35
  36
  37                            ##### How to use this driver #####
  38   ==============================================================================
  39     [..]
  40       This driver is a considered as a driver of service for external devices drivers
  41       that interfaces with the SDMMC peripheral.
  42       According to the device used (SD card/ MMC card / SDMMC card ...), a set of APIs
  43       is used in the device's driver to perform SDMMC operations and functionalities.
  44
  45       This driver is almost transparent for the final user, it is only used to implement other
  46       functionalities of the external device.
  47
  48     [..]
  49       (+) The SDMMC clock (SDMMCCLK = 48 MHz) is coming from a specific output of PLL
  50           (PLL48CLK). Before start working with SDMMC peripheral make sure that the
  51           PLL is well configured.
  52           The SDMMC peripheral uses two clock signals:
  53           (++) SDMMC adapter clock (SDMMCCLK = 48 MHz)
  54           (++) APB2 bus clock (PCLK2)
  55
  56           -@@- PCLK2 and SDMMC_CK clock frequencies must respect the following condition:
  57                Frequency(PCLK2) >= (3 / 8 x Frequency(SDMMC_CK))
  58
  59       (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC
  60           peripheral.
  61
  62       (+) Enable the Power ON State using the SDMMC_PowerState_ON(SDMMCx)
  63           function and disable it using the function SDMMC_PowerState_OFF(SDMMCx).
  64
  65       (+) Enable/Disable the clock using the __SDMMC_ENABLE()/__SDMMC_DISABLE() macros.
  66
  67       (+) Enable/Disable the peripheral interrupts using the macros __SDMMC_ENABLE_IT(hSDMMC, IT)
  68           and __SDMMC_DISABLE_IT(hSDMMC, IT) if you need to use interrupt mode.
  69
  70       (+) When using the DMA mode
  71           (++) Configure the DMA in the MSP layer of the external device
  72           (++) Active the needed channel Request
  73           (++) Enable the DMA using __SDMMC_DMA_ENABLE() macro or Disable it using the macro
  74                __SDMMC_DMA_DISABLE().
  75
  76       (+) To control the CPSM (Command Path State Machine) and send
  77           commands to the card use the SDMMC_SendCommand(SDMMCx),
  78           SDMMC_GetCommandResponse() and SDMMC_GetResponse() functions. First, user has
  79           to fill the command structure (pointer to SDMMC_CmdInitTypeDef) according
  80           to the selected command to be sent.
  81           The parameters that should be filled are:
  82            (++) Command Argument
  83            (++) Command Index
  84            (++) Command Response type
  85            (++) Command Wait
  86            (++) CPSM Status (Enable or Disable).
  87
  88           -@@- To check if the command is well received, read the SDMMC_CMDRESP
  89               register using the SDMMC_GetCommandResponse().
  90               The SDMMC responses registers (SDMMC_RESP1 to SDMMC_RESP2), use the
  91               SDMMC_GetResponse() function.
  92
  93       (+) To control the DPSM (Data Path State Machine) and send/receive
  94            data to/from the card use the SDMMC_DataConfig(), SDMMC_GetDataCounter(),
  95           SDMMC_ReadFIFO(), SDMMC_WriteFIFO() and SDMMC_GetFIFOCount() functions.
  96
  97     *** Read Operations ***
  98     =======================
  99     [..]
 100       (#) First, user has to fill the data structure (pointer to
 101           SDMMC_DataInitTypeDef) according to the selected data type to be received.
 102           The parameters that should be filled are:
 103            (++) Data TimeOut
 104            (++) Data Length
 105            (++) Data Block size
 106            (++) Data Transfer direction: should be from card (To SDMMC)
 107            (++) Data Transfer mode
 108            (++) DPSM Status (Enable or Disable)
 109
 110       (#) Configure the SDMMC resources to receive the data from the card
 111           according to selected transfer mode (Refer to Step 8, 9 and 10).
 112
 113       (#) Send the selected Read command (refer to step 11).
 114
 115       (#) Use the SDMMC flags/interrupts to check the transfer status.
 116
 117     *** Write Operations ***
 118     ========================
 119     [..]
 120      (#) First, user has to fill the data structure (pointer to
 121          SDMMC_DataInitTypeDef) according to the selected data type to be received.
 122          The parameters that should be filled are:
 123           (++) Data TimeOut
 124           (++) Data Length
 125           (++) Data Block size
 126           (++) Data Transfer direction:  should be to card (To CARD)
 127           (++) Data Transfer mode
 128           (++) DPSM Status (Enable or Disable)
 129
 130      (#) Configure the SDMMC resources to send the data to the card according to
 131          selected transfer mode.
 132
 133      (#) Send the selected Write command.
 134
 135      (#) Use the SDMMC flags/interrupts to check the transfer status.
 136
 137     *** Command management operations ***
 138     =====================================
 139     [..]
 140      (#) The commands used for Read/Write//Erase operations are managed in
 141          separate functions.
 142          Each function allows to send the needed command with the related argument,
 143          then check the response.
 144          By the same approach, you could implement a command and check the response.
