+ ==============================================================================
+ ##### SDMMC peripheral features #####
+ ==============================================================================
+ [..] The SD/SDMMC MMC card host interface (SDMMC) provides an interface between the AHB
+ peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDMMC cards and CE-ATA
+ devices.
+
+ [..] The SDMMC features include the following:
+ (+) Full compliance with MultiMediaCard System Specification Version 4.51. Card support
+ for three different databus modes: 1-bit (default), 4-bit and 8-bit.
+ (+) Full compatibility with previous versions of MultiMediaCards (backward compatibility).
+ (+) Full compliance with SD memory card specifications version 4.1.
+ (SDR104 SDMMC_CK speed limited to maximum allowed IO speed, SPI mode and
+ UHS-II mode not supported).
+ (+) Full compliance with SDIO card specification version 4.0. Card support
+ for two different databus modes: 1-bit (default) and 4-bit.
+ (SDR104 SDMMC_CK speed limited to maximum allowed IO speed, SPI mode and
+ UHS-II mode not supported).
+ (+) Data transfer up to 208 Mbyte/s for the 8 bit mode. (depending maximum allowed IO speed).
+ (+) Data and command output enable signals to control external bidirectional drivers
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ This driver is a considered as a driver of service for external devices drivers
+ that interfaces with the SDMMC peripheral.
+ According to the device used (SD card/ MMC card / SDMMC card ...), a set of APIs
+ is used in the device's driver to perform SDMMC operations and functionalities.
+
+ This driver is almost transparent for the final user, it is only used to implement other
+ functionalities of the external device.
+
+ [..]
+ (+) The SDMMC clock is coming from output of PLL1_Q or PLL2_R.
+ Before start working with SDMMC peripheral make sure that the PLL is well configured.
+ The SDMMC peripheral uses two clock signals:
+ (++) PLL1_Q bus clock (default after reset)
+ (++) PLL2_R bus clock
+
+ (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC
+ peripheral.
+
+ (+) Enable the Power ON State using the SDMMC_PowerState_ON(SDMMCx)
+ function and disable it using the function SDMMC_PowerState_OFF(SDMMCx).
+
+ (+) Enable/Disable the peripheral interrupts using the macros __SDMMC_ENABLE_IT(hSDMMC, IT)
+ and __SDMMC_DISABLE_IT(hSDMMC, IT) if you need to use interrupt mode.
+
+ (+) When using the DMA mode
+ (++) Configure the IDMA mode (Single buffer or double)
+ (++) Configure the buffer address
+ (++) Configure Data Path State Machine
+
+ (+) To control the CPSM (Command Path State Machine) and send
+ commands to the card use the SDMMC_SendCommand(SDMMCx),
+ SDMMC_GetCommandResponse() and SDMMC_GetResponse() functions. First, user has
+ to fill the command structure (pointer to SDMMC_CmdInitTypeDef) according
+ to the selected command to be sent.
+ The parameters that should be filled are:
+ (++) Command Argument
+ (++) Command Index
+ (++) Command Response type
+ (++) Command Wait
+ (++) CPSM Status (Enable or Disable).
+
+ -@@- To check if the command is well received, read the SDMMC_CMDRESP
+ register using the SDMMC_GetCommandResponse().
+ The SDMMC responses registers (SDMMC_RESP1 to SDMMC_RESP2), use the
+ SDMMC_GetResponse() function.
+
+ (+) To control the DPSM (Data Path State Machine) and send/receive
+ data to/from the card use the SDMMC_DataConfig(), SDMMC_GetDataCounter(),
+ SDMMC_ReadFIFO(), SDMMC_WriteFIFO() and SDMMC_GetFIFOCount() functions.
+
+ *** Read Operations ***
+ =======================
+ [..]
+ (#) First, user has to fill the data structure (pointer to
+ SDMMC_DataInitTypeDef) according to the selected data type to be received.
+ The parameters that should be filled are:
+ (++) Data TimeOut
+ (++) Data Length
+ (++) Data Block size
+ (++) Data Transfer direction: should be from card (To SDMMC)
+ (++) Data Transfer mode
+ (++) DPSM Status (Enable or Disable)
+
+ (#) Configure the SDMMC resources to receive the data from the card
+ according to selected transfer mode (Refer to Step 8, 9 and 10).
+
+ (#) Send the selected Read command (refer to step 11).
+
+ (#) Use the SDMMC flags/interrupts to check the transfer status.
+
+ *** Write Operations ***
+ ========================
+ [..]
+ (#) First, user has to fill the data structure (pointer to
+ SDMMC_DataInitTypeDef) according to the selected data type to be received.
+ The parameters that should be filled are:
+ (++) Data TimeOut
+ (++) Data Length
+ (++) Data Block size
+ (++) Data Transfer direction: should be to card (To CARD)
+ (++) Data Transfer mode
+ (++) DPSM Status (Enable or Disable)
+
+ (#) Configure the SDMMC resources to send the data to the card according to
+ selected transfer mode.
+
+ (#) Send the selected Write command.
+
+ (#) Use the SDMMC flags/interrupts to check the transfer status.
+
+ *** Command management operations ***
+ =====================================
+ [..]
+ (#) The commands used for Read/Write/Erase operations are managed in
+ separate functions.
+ Each function allows to send the needed command with the related argument,
+ then check the response.
+ By the same approach, you could implement a command and check the response.
