+ * + Peripheral State functions

+ @verbatim
+ ==============================================================================
+ ##### 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 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 (MSI, PLLUSB1CLK,
+ PLLUSB2CLK). 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()
+ function and disable it using the function SDIO_PowerState_OFF().
+
+ (+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros.
+
+ (+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT()
+ and __SDIO_DISABLE_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_DataConfig(), 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 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 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 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.
