- ==============================================================================
- ##### 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 MultiMediaCard System Specification Version 4.51. Card support
- for three different databus modes: 1-bit (default), 4-bit and 8-bit.
- (+) Full compatibility with previous versions of MultiMediaCards (backward compatibility).
- (+) Full compliance with SD memory card specifications version 4.1.
- (SDR104 SDMMC_CK speed limited to maximum allowed IO speed, SPI mode and
- UHS-II mode not supported).
- (+) Full compliance with SDIO card specification version 4.0. Card support
- for two different databus modes: 1-bit (default) and 4-bit.
- (SDR104 SDMMC_CK speed limited to maximum allowed IO speed, SPI mode and
- UHS-II mode not supported).
- (+) Data transfer up to 208 Mbyte/s for the 8 bit mode. (depending maximum allowed IO speed).
- (+) 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 is coming from output of PLL1_Q or PLL2_R.
- Before start working with SDMMC peripheral make sure that the PLL is well configured.
- The SDMMC peripheral uses two clock signals:
- (++) PLL1_Q bus clock (default after reset)
- (++) PLL2_R bus clock
-
- (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC
- peripheral.
-
- (+) Enable the Power ON State using the SDMMC_PowerState_ON(SDMMCx)
- function and disable it using the function SDMMC_PowerState_OFF(SDMMCx).
-
- (+) Enable/Disable the peripheral interrupts using the macros __SDMMC_ENABLE_IT(hSDMMC, IT)
- and __SDMMC_DISABLE_IT(hSDMMC, IT) if you need to use interrupt mode.
-
- (+) When using the DMA mode
- (++) Configure the IDMA mode (Single buffer or double)
- (++) Configure the buffer address
- (++) Configure Data Path State Machine
-
- (+) To control the CPSM (Command Path State Machine) and send
- commands to the card use the SDMMC_SendCommand(SDMMCx),
- SDMMC_GetCommandResponse() and SDMMC_GetResponse() functions. First, user has
- to fill the command structure (pointer to SDMMC_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 SDMMC_CMDRESP
- register using the SDMMC_GetCommandResponse().
- The SDMMC responses registers (SDMMC_RESP1 to SDMMC_RESP2), use the
- SDMMC_GetResponse() function.
-
- (+) To control the DPSM (Data Path State Machine) and send/receive
- data to/from the card use the SDMMC_DataConfig(), SDMMC_GetDataCounter(),
- SDMMC_ReadFIFO(), SDMMC_WriteFIFO() and SDMMC_GetFIFOCount() functions.
-
- *** Read Operations ***
- =======================
- [..]
- (#) First, user has to fill the data structure (pointer to
- SDMMC_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 SDMMC flags/interrupts to check the transfer status.
-
- *** Write Operations ***
- ========================
- [..]
- (#) First, user has to fill the data structure (pointer to
- SDMMC_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 SDMMC 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.
