 | |
|                          ##### How to use this driver #####
 | |
|   ==============================================================================
 | |
|     [..]
 | |
|       This driver is a generic layered driver which contains a set of APIs used to
 | |
|       control NAND flash memories. It uses the FMC layer functions to interface
 | |
|       with NAND devices. This driver is used as follows:
 | |
| 
 | |
|       (+) NAND flash memory configuration sequence using the function HAL_NAND_Init()
 | |
|           with control and timing parameters for both common and attribute spaces.
 | |
| 
 | |
|       (+) Read NAND flash memory maker and device IDs using the function
 | |
|           HAL_NAND_Read_ID(). The read information is stored in the NAND_ID_TypeDef
 | |
|           structure declared by the function caller.
 | |
| 
 | |
|       (+) Access NAND flash memory by read/write operations using the functions
 | |
|           HAL_NAND_Read_Page_8b()/HAL_NAND_Read_SpareArea_8b(),
 | |
|           HAL_NAND_Write_Page_8b()/HAL_NAND_Write_SpareArea_8b(),
 | |
|           HAL_NAND_Read_Page_16b()/HAL_NAND_Read_SpareArea_16b(),
 | |
|           HAL_NAND_Write_Page_16b()/HAL_NAND_Write_SpareArea_16b()
 | |
|           to read/write page(s)/spare area(s). These functions use specific device
 | |
|           information (Block, page size..) predefined by the user in the NAND_DeviceConfigTypeDef
 | |
|           structure. The read/write address information is contained by the Nand_Address_Typedef
 | |
|           structure passed as parameter.
 | |
| 
 | |
|       (+) Perform NAND flash Reset chip operation using the function HAL_NAND_Reset().
 | |
| 
 | |
|       (+) Perform NAND flash erase block operation using the function HAL_NAND_Erase_Block().
 | |
|           The erase block address information is contained in the Nand_Address_Typedef
 | |
|           structure passed as parameter.
 | |
| 
 | |
|       (+) Read the NAND flash status operation using the function HAL_NAND_Read_Status().
 | |
| 
 | |
|       (+) You can also control the NAND device by calling the control APIs HAL_NAND_ECC_Enable()/
 | |
|           HAL_NAND_ECC_Disable() to respectively enable/disable the ECC code correction
 | |
|           feature or the function HAL_NAND_GetECC() to get the ECC correction code.
 | |
| 
 | |
|       (+) You can monitor the NAND device HAL state by calling the function
 | |
|           HAL_NAND_GetState()
 | |
| 
 | |
|     [..]
 | |
|       (@) This driver is a set of generic APIs which handle standard NAND flash operations.
 | |
|           If a NAND flash device contains different operations and/or implementations,
 | |
|           it should be implemented separately.
 | |
| 
 | |
|     *** Callback registration ***
 | |
|     =============================================
 | |
|     [..]
 | |
|       The compilation define  USE_HAL_NAND_REGISTER_CALLBACKS when set to 1
 | |
|       allows the user to configure dynamically the driver callbacks.
 | |
| 
 | |
|       Use Functions HAL_NAND_RegisterCallback() to register a user callback,
 | |
|       it allows to register following callbacks:
 | |
|         (+) MspInitCallback    : NAND MspInit.
 | |
|         (+) MspDeInitCallback  : NAND MspDeInit.
 | |
|       This function takes as parameters the HAL peripheral handle, the Callback ID
 | |
|       and a pointer to the user callback function.
 | |
| 
 | |
|       Use function HAL_NAND_UnRegisterCallback() to reset a callback to the default
 | |
|       weak (surcharged) function. It allows to reset following callbacks:
 | |
|         (+) MspInitCallback    : NAND MspInit.
 | |
|         (+) MspDeInitCallback  : NAND MspDeInit.
 | |
|       This function) takes as parameters the HAL peripheral handle and the Callback ID.
 | |
| 
 | |
|       By default, after the HAL_NAND_Init and if the state is HAL_NAND_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 HAL_NAND_Init
 | |
|       and  HAL_NAND_DeInit only when these callbacks are null (not registered beforehand).
 | |
|       If not, MspInit or MspDeInit are not null, the HAL_NAND_Init and HAL_NAND_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 HAL_NAND_RegisterCallback before calling HAL_NAND_DeInit
 | |
|       or HAL_NAND_Init function.
 | |
| 
 | |
|       When The compilation define USE_HAL_NAND_REGISTER_CALLBACKS is set to 0 or
 | |
|       not defined, the callback registering feature is not available
 | |
|       and weak (surcharged) callbacks are used.
