+  ==============================================================================
+                       ##### SDMMC peripheral features #####
+  ==============================================================================        
+    [..] The SD/SDMMC MMC card host interface (SDMMC) provides an interface between the APB2
+         peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDMMC cards and CE-ATA
+         devices.
+    
+    [..] The SDMMC features include the following:
+         (+) Full compliance with MultiMedia Card System Specification Version 4.2. Card support
+             for three different databus modes: 1-bit (default), 4-bit and 8-bit
+         (+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility)
+         (+) Full compliance with SD Memory Card Specifications Version 2.0
+         (+) Full compliance with SD I/O Card Specification Version 2.0: card support for two
+             different data bus modes: 1-bit (default) and 4-bit
+         (+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol
+             Rev1.1)
+         (+) Data transfer up to 48 MHz for the 8 bit mode
+         (+) 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 (SDMMCCLK = 48 MHz) is coming from a specific output of PLL 
+          (PLL48CLK). Before start working with SDMMC peripheral make sure that the
+          PLL is well configured.
+          The SDMMC peripheral uses two clock signals:
+          (++) SDMMC adapter clock (SDMMCCLK = 48 MHz)
+          (++) APB2 bus clock (PCLK2)
+       
+          -@@- PCLK2 and SDMMC_CK clock frequencies must respect the following condition:
+               Frequency(PCLK2) >= (3 / 8 x Frequency(SDMMC_CK))
+  
+      (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC
+          peripheral.
+
+      (+) Enable the Power ON State using the SDIO_PowerState_ON(SDIOx) 
+          function and disable it using the function SDIO_PowerState_ON(SDIOx).
+                
+      (+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros.
+  
+      (+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT(hSDIO, IT) 
+          and __SDIO_DISABLE_IT(hSDIO, IT) if you need to use interrupt mode. 
+  
+      (+) When using the DMA mode 
+          (++) Configure the DMA in the MSP layer of the external device
+          (++) Active the needed channel Request 
+          (++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro
+               __SDIO_DMA_DISABLE().
+  
+      (+) To control the CPSM (Command Path State Machine) and send 
+          commands to the card use the SDIO_SendCommand(), 
+          SDIO_GetCommandResponse() and SDIO_GetResponse() functions. First, user has
+          to fill the command structure (pointer to SDIO_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 SDIO_CMDRESP
+              register using the SDIO_GetCommandResponse().
+              The SDMMC responses registers (SDIO_RESP1 to SDIO_RESP2), use the
+              SDIO_GetResponse() function.
+  
+      (+) To control the DPSM (Data Path State Machine) and send/receive 
+           data to/from the card use the SDIO_ConfigData(), SDIO_GetDataCounter(), 
+          SDIO_ReadFIFO(), SDIO_WriteFIFO() and SDIO_GetFIFOCount() functions.
+  
+    *** Read Operations ***
+    =======================
+    [..]
+      (#) First, user has to fill the data structure (pointer to
+          SDIO_DataInitTypeDef) according to the selected data type to be received.
+          The parameters that should be filled are:

+           (++) 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 SDIO flags/interrupts to check the transfer status.
+  
+    *** Write Operations ***
+    ========================
+    [..]
+     (#) First, user has to fill the data structure (pointer to
+         SDIO_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 SDIO 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.
