* @version V1.1.1
* @date 12-May-2017
* @brief NAND HAL module driver.
* This file provides a generic firmware to drive NAND 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 NAND flash memories. It uses the FSMC 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.
