<> 144:ef7eb2e8f9f7 18 ##### SDMMC peripheral features #####
<> 144:ef7eb2e8f9f7 19 ==============================================================================
<> 144:ef7eb2e8f9f7 20 [..] The SD/SDIO MMC card host interface (SDIO) provides an interface between the APB2
<> 144:ef7eb2e8f9f7 21 peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDIO cards and CE-ATA
<> 144:ef7eb2e8f9f7 22 devices.
<> 144:ef7eb2e8f9f7 23
<> 144:ef7eb2e8f9f7 24 [..] The SDIO features include the following:
<> 144:ef7eb2e8f9f7 25 (+) Full compliance with MultiMedia Card System Specification Version 4.2. Card support
<> 144:ef7eb2e8f9f7 26 for three different databus modes: 1-bit (default), 4-bit and 8-bit
<> 144:ef7eb2e8f9f7 27 (+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility)
<> 144:ef7eb2e8f9f7 28 (+) Full compliance with SD Memory Card Specifications Version 2.0
<> 144:ef7eb2e8f9f7 29 (+) Full compliance with SD I/O Card Specification Version 2.0: card support for two
<> 144:ef7eb2e8f9f7 30 different data bus modes: 1-bit (default) and 4-bit
<> 144:ef7eb2e8f9f7 31 (+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol

<> 144:ef7eb2e8f9f7 37 ##### How to use this driver #####
<> 144:ef7eb2e8f9f7 38 ==============================================================================
<> 144:ef7eb2e8f9f7 39 [..]
<> 144:ef7eb2e8f9f7 40 This driver is a considered as a driver of service for external devices drivers
<> 144:ef7eb2e8f9f7 41 that interfaces with the SDIO peripheral.
<> 144:ef7eb2e8f9f7 42 According to the device used (SD card/ MMC card / SDIO card ...), a set of APIs
<> 144:ef7eb2e8f9f7 43 is used in the device's driver to perform SDIO operations and functionalities.
<> 144:ef7eb2e8f9f7 44
<> 144:ef7eb2e8f9f7 45 This driver is almost transparent for the final user, it is only used to implement other
<> 144:ef7eb2e8f9f7 46 functionalities of the external device.
<> 144:ef7eb2e8f9f7 47
<> 144:ef7eb2e8f9f7 48 [..]
<> 144:ef7eb2e8f9f7 49 (+) The SDIO clock (SDIOCLK = 48 MHz) is coming from a specific output of PLL
<> 144:ef7eb2e8f9f7 50 (PLL48CLK). Before start working with SDIO peripheral make sure that the
<> 144:ef7eb2e8f9f7 51 PLL is well configured.
<> 144:ef7eb2e8f9f7 52 The SDIO peripheral uses two clock signals:
<> 144:ef7eb2e8f9f7 53 (++) SDIO adapter clock (SDIOCLK = 48 MHz)
<> 144:ef7eb2e8f9f7 54 (++) APB2 bus clock (PCLK2)
<> 144:ef7eb2e8f9f7 55
<> 144:ef7eb2e8f9f7 56 -@@- PCLK2 and SDIO_CK clock frequencies must respect the following condition:
<> 144:ef7eb2e8f9f7 57 Frequency(PCLK2) >= (3 / 8 x Frequency(SDIO_CK))
<> 144:ef7eb2e8f9f7 58
<> 144:ef7eb2e8f9f7 59 (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDIO
<> 144:ef7eb2e8f9f7 60 peripheral.
<> 144:ef7eb2e8f9f7 61
<> 144:ef7eb2e8f9f7 62 (+) Enable the Power ON State using the SDIO_PowerState_ON(SDIOx)
<> 144:ef7eb2e8f9f7 63 function and disable it using the function SDIO_PowerState_OFF(SDIOx).
<> 144:ef7eb2e8f9f7 64
<> 144:ef7eb2e8f9f7 65 (+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros.
<> 144:ef7eb2e8f9f7 66
<> 144:ef7eb2e8f9f7 67 (+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT(hsdio, IT)
<> 144:ef7eb2e8f9f7 68 and __SDIO_DISABLE_IT(hsdio, IT) if you need to use interrupt mode.
<> 144:ef7eb2e8f9f7 69
<> 144:ef7eb2e8f9f7 70 (+) When using the DMA mode
<> 144:ef7eb2e8f9f7 71 (++) Configure the DMA in the MSP layer of the external device
<> 144:ef7eb2e8f9f7 72 (++) Active the needed channel Request
<> 144:ef7eb2e8f9f7 73 (++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro
<> 144:ef7eb2e8f9f7 74 __SDIO_DMA_DISABLE().
<> 144:ef7eb2e8f9f7 75
<> 144:ef7eb2e8f9f7 76 (+) To control the CPSM (Command Path State Machine) and send
<> 144:ef7eb2e8f9f7 77 commands to the card use the SDIO_SendCommand(SDIOx),
<> 144:ef7eb2e8f9f7 78 SDIO_GetCommandResponse() and SDIO_GetResponse() functions. First, user has
<> 144:ef7eb2e8f9f7 79 to fill the command structure (pointer to SDIO_CmdInitTypeDef) according
<> 144:ef7eb2e8f9f7 80 to the selected command to be sent.

<> 144:ef7eb2e8f9f7 85 (++) Command Wait
<> 144:ef7eb2e8f9f7 86 (++) CPSM Status (Enable or Disable).
<> 144:ef7eb2e8f9f7 87
<> 144:ef7eb2e8f9f7 88 -@@- To check if the command is well received, read the SDIO_CMDRESP
<> 144:ef7eb2e8f9f7 89 register using the SDIO_GetCommandResponse().
<> 144:ef7eb2e8f9f7 90 The SDIO responses registers (SDIO_RESP1 to SDIO_RESP2), use the
<> 144:ef7eb2e8f9f7 91 SDIO_GetResponse() function.
<> 144:ef7eb2e8f9f7 92
<> 144:ef7eb2e8f9f7 93 (+) To control the DPSM (Data Path State Machine) and send/receive
<> 144:ef7eb2e8f9f7 94 data to/from the card use the SDIO_DataConfig(), SDIO_GetDataCounter(),
<> 144:ef7eb2e8f9f7 95 SDIO_ReadFIFO(), DIO_WriteFIFO() and SDIO_GetFIFOCount() functions.
