ganlikun	0:13413ea9a877	17	==============================================================================
ganlikun	0:13413ea9a877	18	##### SDMMC peripheral features #####
ganlikun	0:13413ea9a877	19	==============================================================================
ganlikun	0:13413ea9a877	20	[..] The SD/SDMMC MMC card host interface (SDMMC) provides an interface between the APB2
ganlikun	0:13413ea9a877	21	peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDMMC cards and CE-ATA
ganlikun	0:13413ea9a877	22	devices.
ganlikun	0:13413ea9a877	23
ganlikun	0:13413ea9a877	24	[..] The SDMMC features include the following:
ganlikun	0:13413ea9a877	25	(+) Full compliance with MultiMedia Card System Specification Version 4.2. Card support
ganlikun	0:13413ea9a877	26	for three different databus modes: 1-bit (default), 4-bit and 8-bit
ganlikun	0:13413ea9a877	27	(+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility)
ganlikun	0:13413ea9a877	28	(+) Full compliance with SD Memory Card Specifications Version 2.0
ganlikun	0:13413ea9a877	29	(+) Full compliance with SD I/O Card Specification Version 2.0: card support for two
ganlikun	0:13413ea9a877	30	different data bus modes: 1-bit (default) and 4-bit
ganlikun	0:13413ea9a877	31	(+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol
ganlikun	0:13413ea9a877	32	Rev1.1)
ganlikun	0:13413ea9a877	33	(+) Data transfer up to 48 MHz for the 8 bit mode
ganlikun	0:13413ea9a877	34	(+) Data and command output enable signals to control external bidirectional drivers.
ganlikun	0:13413ea9a877	35
ganlikun	0:13413ea9a877	36
ganlikun	0:13413ea9a877	37	##### How to use this driver #####
ganlikun	0:13413ea9a877	38	==============================================================================
ganlikun	0:13413ea9a877	39	[..]
ganlikun	0:13413ea9a877	40	This driver is a considered as a driver of service for external devices drivers
ganlikun	0:13413ea9a877	41	that interfaces with the SDMMC peripheral.
ganlikun	0:13413ea9a877	42	According to the device used (SD card/ MMC card / SDMMC card ...), a set of APIs
ganlikun	0:13413ea9a877	43	is used in the device's driver to perform SDMMC operations and functionalities.
ganlikun	0:13413ea9a877	44
ganlikun	0:13413ea9a877	45	This driver is almost transparent for the final user, it is only used to implement other
ganlikun	0:13413ea9a877	46	functionalities of the external device.
ganlikun	0:13413ea9a877	47
ganlikun	0:13413ea9a877	48	[..]
ganlikun	0:13413ea9a877	49	(+) The SDMMC clock (SDMMCCLK = 48 MHz) is coming from a specific output of PLL
ganlikun	0:13413ea9a877	50	(PLL48CLK). Before start working with SDMMC peripheral make sure that the
ganlikun	0:13413ea9a877	51	PLL is well configured.
ganlikun	0:13413ea9a877	52	The SDMMC peripheral uses two clock signals:
ganlikun	0:13413ea9a877	53	(++) SDMMC adapter clock (SDMMCCLK = 48 MHz)
ganlikun	0:13413ea9a877	54	(++) APB2 bus clock (PCLK2)
ganlikun	0:13413ea9a877	55
ganlikun	0:13413ea9a877	56	-@@- PCLK2 and SDMMC_CK clock frequencies must respect the following condition:
ganlikun	0:13413ea9a877	57	Frequency(PCLK2) >= (3 / 8 x Frequency(SDMMC_CK))
ganlikun	0:13413ea9a877	58
ganlikun	0:13413ea9a877	59	(+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC
ganlikun	0:13413ea9a877	60	peripheral.
ganlikun	0:13413ea9a877	61
ganlikun	0:13413ea9a877	62	(+) Enable the Power ON State using the SDIO_PowerState_ON(SDIOx)
ganlikun	0:13413ea9a877	63	function and disable it using the function SDIO_PowerState_ON(SDIOx).
ganlikun	0:13413ea9a877	64
ganlikun	0:13413ea9a877	65	(+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros.
ganlikun	0:13413ea9a877	66
ganlikun	0:13413ea9a877	67	(+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT(hSDIO, IT)
ganlikun	0:13413ea9a877	68	and __SDIO_DISABLE_IT(hSDIO, IT) if you need to use interrupt mode.
ganlikun	0:13413ea9a877	69
ganlikun	0:13413ea9a877	70	(+) When using the DMA mode
ganlikun	0:13413ea9a877	71	(++) Configure the DMA in the MSP layer of the external device
ganlikun	0:13413ea9a877	72	(++) Active the needed channel Request
ganlikun	0:13413ea9a877	73	(++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro
ganlikun	0:13413ea9a877	74	__SDIO_DMA_DISABLE().
ganlikun	0:13413ea9a877	75
ganlikun	0:13413ea9a877	76	(+) To control the CPSM (Command Path State Machine) and send
ganlikun	0:13413ea9a877	77	commands to the card use the SDIO_SendCommand(),
ganlikun	0:13413ea9a877	78	SDIO_GetCommandResponse() and SDIO_GetResponse() functions. First, user has
ganlikun	0:13413ea9a877	79	to fill the command structure (pointer to SDIO_CmdInitTypeDef) according
ganlikun	0:13413ea9a877	80	to the selected command to be sent.
ganlikun	0:13413ea9a877	81	The parameters that should be filled are:
ganlikun	0:13413ea9a877	82	(++) Command Argument
ganlikun	0:13413ea9a877	83	(++) Command Index
ganlikun	0:13413ea9a877	84	(++) Command Response type
ganlikun	0:13413ea9a877	85	(++) Command Wait
ganlikun	0:13413ea9a877	86	(++) CPSM Status (Enable or Disable).
ganlikun	0:13413ea9a877	87
ganlikun	0:13413ea9a877	88	-@@- To check if the command is well received, read the SDIO_CMDRESP
ganlikun	0:13413ea9a877	89	register using the SDIO_GetCommandResponse().
ganlikun	0:13413ea9a877	90	The SDMMC responses registers (SDIO_RESP1 to SDIO_RESP2), use the
ganlikun	0:13413ea9a877	91	SDIO_GetResponse() function.
ganlikun	0:13413ea9a877	92
ganlikun	0:13413ea9a877	93	(+) To control the DPSM (Data Path State Machine) and send/receive
ganlikun	0:13413ea9a877	94	data to/from the card use the SDIO_ConfigData(), SDIO_GetDataCounter(),
ganlikun	0:13413ea9a877	95	SDIO_ReadFIFO(), SDIO_WriteFIFO() and SDIO_GetFIFOCount() functions.
ganlikun	0:13413ea9a877	96
