		16	##### SDMMC peripheral features #####
		17	==============================================================================
		18	[..] The SD/SDMMC MMC card host interface (SDMMC) provides an interface between the AHB
		19	peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDMMC cards and CE-ATA
		20	devices.
		21
		22	[..] The SDMMC features include the following:
		23	(+) Full compliance with MultiMedia Card System Specification Version 4.2. Card support
		24	for three different databus modes: 1-bit (default), 4-bit and 8-bit
		25	(+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility)
		26	(+) Full compliance with SD Memory Card Specifications Version 2.0
		27	(+) Full compliance with SD I/O Card Specification Version 2.0: card support for two
		28	different data bus modes: 1-bit (default) and 4-bit
		29	(+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol
		30	Rev1.1)
		31	(+) Data transfer up to 48 MHz for the 8 bit mode
		32	(+) Data and command output enable signals to control external bidirectional drivers
		33
		34	##### How to use this driver #####
		35	==============================================================================
		36	[..]
		37	This driver is a considered as a driver of service for external devices drivers
		38	that interfaces with the SDMMC peripheral.
		39	According to the device used (SD card/ MMC card / SDMMC card ...), a set of APIs
		40	is used in the device's driver to perform SDMMC operations and functionalities.
		41
		42	This driver is almost transparent for the final user, it is only used to implement other
		43	functionalities of the external device.
		44
		45	[..]
		46	(+) The SDMMC clock (SDMMCCLK = 48 MHz) is coming from a specific output (MSI, PLLUSB1CLK,
		47	PLLUSB2CLK). Before start working with SDMMC peripheral make sure that the
		48	PLL is well configured.
		49	The SDMMC peripheral uses two clock signals:
		50	(++) SDMMC adapter clock (SDMMCCLK = 48 MHz)
		51	(++) APB2 bus clock (PCLK2)
		52
		53	-@@- PCLK2 and SDMMC_CK clock frequencies must respect the following condition:
		54	Frequency(PCLK2) >= (3 / 8 x Frequency(SDMMC_CK))
		55
		56	(+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC
		57	peripheral.
		58
		59	(+) Enable the Power ON State using the SDIO_PowerState_ON()
		60	function and disable it using the function SDIO_PowerState_OFF().
		61
		62	(+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros.
		63
		64	(+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT()
		65	and __SDIO_DISABLE_IT() if you need to use interrupt mode.
		66
		67	(+) When using the DMA mode
		68	(++) Configure the DMA in the MSP layer of the external device
		69	(++) Active the needed channel Request
		70	(++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro
		71	__SDIO_DMA_DISABLE().
		72
		73	(+) To control the CPSM (Command Path State Machine) and send
		74	commands to the card use the SDIO_SendCommand(),
		75	SDIO_GetCommandResponse() and SDIO_GetResponse() functions. First, user has
		76	to fill the command structure (pointer to SDIO_CmdInitTypeDef) according
		77	to the selected command to be sent.
		78	The parameters that should be filled are:
		79	(++) Command Argument
		80	(++) Command Index
		81	(++) Command Response type
		82	(++) Command Wait
		83	(++) CPSM Status (Enable or Disable).
		84
		85	-@@- To check if the command is well received, read the SDIO_CMDRESP
		86	register using the SDIO_GetCommandResponse().
		87	The SDMMC responses registers (SDIO_RESP1 to SDIO_RESP2), use the
		88	SDIO_GetResponse() function.
		89
		90	(+) To control the DPSM (Data Path State Machine) and send/receive
		91	data to/from the card use the SDIO_DataConfig(), SDIO_GetDataCounter(),
		92	SDIO_ReadFIFO(), SDIO_WriteFIFO() and SDIO_GetFIFOCount() functions.
		93
		94	* Read Operations *
		95	=======================
		96	[..]
		97	(#) First, user has to fill the data structure (pointer to
		98	SDIO_DataInitTypeDef) according to the selected data type to be received.
		99	The parameters that should be filled are:
		100	(++) Data TimeOut
		101	(++) Data Length
		102	(++) Data Block size
		103	(++) Data Transfer direction: should be from card (To SDMMC)
		104	(++) Data Transfer mode
		105	(++) DPSM Status (Enable or Disable)
		106
		107	(#) Configure the SDMMC resources to receive the data from the card
		108	according to selected transfer mode (Refer to Step 8, 9 and 10).
		109
		110	(#) Send the selected Read command (refer to step 11).
		111
		112	(#) Use the SDIO flags/interrupts to check the transfer status.
		113
		114	* Write Operations *
		115	========================
		116	[..]
		117	(#) First, user has to fill the data structure (pointer to
		118	SDIO_DataInitTypeDef) according to the selected data type to be received.
		119	The parameters that should be filled are:
		120	(++) Data TimeOut
		121	(++) Data Length
		122	(++) Data Block size
		123	(++) Data Transfer direction: should be to card (To CARD)
		124	(++) Data Transfer mode
		125	(++) DPSM Status (Enable or Disable)
		126
		127	(#) Configure the SDMMC resources to send the data to the card according to
		128	selected transfer mode.
		129
		130	(#) Send the selected Write command.
		131
		132	(#) Use the SDIO flags/interrupts to check the transfer status.
		133
		134	* Command management operations *
		135	=====================================
		136	[..]
		137	(#) The commands used for Read/Write/Erase operations are managed in
		138	separate functions.
		139	Each function allows to send the needed command with the related argument,
		140	then check the response.
		141	By the same approach, you could implement a command and check the response.
