+ * @brief SDRAM HAL module driver.
+ * This file provides a generic firmware to drive SDRAM memories mounted
+ * as external device.
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ This driver is a generic layered driver which contains a set of APIs used to
+ control SDRAM memories. It uses the FMC layer functions to interface
+ with SDRAM devices.
+ The following sequence should be followed to configure the FMC to interface
+ with SDRAM memories:
+
+ (#) Declare a SDRAM_HandleTypeDef handle structure, for example:
+ SDRAM_HandleTypeDef hsdram
+
+ (++) Fill the SDRAM_HandleTypeDef handle "Init" field with the allowed
+ values of the structure member.
+
+ (++) Fill the SDRAM_HandleTypeDef handle "Instance" field with a predefined
+ base register instance for NOR or SDRAM device
+
+ (#) Declare a FMC_SDRAM_TimingTypeDef structure; for example:
+ FMC_SDRAM_TimingTypeDef Timing;
+ and fill its fields with the allowed values of the structure member.
+
+ (#) Initialize the SDRAM Controller by calling the function HAL_SDRAM_Init(). This function
+ performs the following sequence:
+
+ (##) MSP hardware layer configuration using the function HAL_SDRAM_MspInit()
+ (##) Control register configuration using the FMC SDRAM interface function
+ FMC_SDRAM_Init()
+ (##) Timing register configuration using the FMC SDRAM interface function
+ FMC_SDRAM_Timing_Init()
+ (##) Program the SDRAM external device by applying its initialization sequence
+ according to the device plugged in your hardware. This step is mandatory
+ for accessing the SDRAM device.
+
+ (#) At this stage you can perform read/write accesses from/to the memory connected
+ to the SDRAM Bank. You can perform either polling or DMA transfer using the
+ following APIs:
+ (++) HAL_SDRAM_Read()/HAL_SDRAM_Write() for polling read/write access
+ (++) HAL_SDRAM_Read_DMA()/HAL_SDRAM_Write_DMA() for DMA read/write transfer
+
+ (#) You can also control the SDRAM device by calling the control APIs HAL_SDRAM_WriteOperation_Enable()/
+ HAL_SDRAM_WriteOperation_Disable() to respectively enable/disable the SDRAM write operation or
+ the function HAL_SDRAM_SendCommand() to send a specified command to the SDRAM
+ device. The command to be sent must be configured with the FMC_SDRAM_CommandTypeDef
+ structure.
+
+ (#) You can continuously monitor the SDRAM device HAL state by calling the function
+ HAL_SDRAM_GetState()
+
+ *** Callback registration ***
+ =============================================
+ [..]
+ The compilation define USE_HAL_SDRAM_REGISTER_CALLBACKS when set to 1
+ allows the user to configure dynamically the driver callbacks.
+
+ Use Functions @ref HAL_SDRAM_RegisterCallback() to register a user callback,
+ it allows to register following callbacks:
+ (+) MspInitCallback : SDRAM MspInit.
+ (+) MspDeInitCallback : SDRAM MspDeInit.
+ This function takes as parameters the HAL peripheral handle, the Callback ID
+ and a pointer to the user callback function.
+
+ Use function @ref HAL_SDRAM_UnRegisterCallback() to reset a callback to the default
+ weak (surcharged) function. It allows to reset following callbacks:
+ (+) MspInitCallback : SDRAM MspInit.
+ (+) MspDeInitCallback : SDRAM MspDeInit.
+ This function) takes as parameters the HAL peripheral handle and the Callback ID.
+
+ By default, after the @ref HAL_SDRAM_Init and if the state is HAL_SDRAM_STATE_RESET
+ all callbacks are reset to the corresponding legacy weak (surcharged) functions.
+ Exception done for MspInit and MspDeInit callbacks that are respectively
+ reset to the legacy weak (surcharged) functions in the @ref HAL_SDRAM_Init
+ and @ref HAL_SDRAM_DeInit only when these callbacks are null (not registered beforehand).
+ If not, MspInit or MspDeInit are not null, the @ref HAL_SDRAM_Init and @ref HAL_SDRAM_DeInit
+ keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
+
+ Callbacks can be registered/unregistered in READY state only.
+ Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
+ in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
+ during the Init/DeInit.
+ In that case first register the MspInit/MspDeInit user callbacks
+ using @ref HAL_SDRAM_RegisterCallback before calling @ref HAL_SDRAM_DeInit
+ or @ref HAL_SDRAM_Init function.
+
+ When The compilation define USE_HAL_SDRAM_REGISTER_CALLBACKS is set to 0 or
+ not defined, the callback registering feature is not available
+ and weak (surcharged) callbacks are used.
