| ##### 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. |
