30.2 NOR Firmware driver API description
30.2.1 How to use this driver
This driver is a generic layered driver which contains a set of APIs used to control NOR
flash memories. It uses the FSMC layer functions to interface with NOR devices. This
driver is used as follows:
NOR flash memory configuration sequence using the function HAL_NOR_Init() with
control and timing parameters for both normal and extended mode.
Read NOR flash memory manufacturer code and device IDs using the function
HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef
structure declared by the function caller.
Access NOR flash memory by read/write data unit operations using the functions
HAL_NOR_Read(), HAL_NOR_Program().
Perform NOR flash erase block/chip operations using the functions
HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip().
Read the NOR flash CFI (common flash interface) IDs using the function
HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef
structure declared by the function caller.
You can also control the NOR device by calling the control APIs
HAL_NOR_WriteOperation_Enable()/ HAL_NOR_WriteOperation_Disable() to
respectively enable/disable the NOR write operation
You can monitor the NOR device HAL state by calling the function
HAL_NOR_GetState()
This driver is a set of generic APIs which handle standard NOR flash operations.
If a NOR flash device contains different operations and/or implementations, it
should be implemented separately.
NOR HAL driver macros list
Below the list of most used macros in NOR HAL driver.
NOR_WRITE : NOR memory write data to specified address
30.2.2 NOR Initialization and de_initialization functions
This section provides functions allowing to initialize/de-initialize the NOR memory
This section contains the following APIs:
HAL_NOR_Init()
HAL_NOR_DeInit()
HAL_NOR_MspInit()
HAL_NOR_MspDeInit()
HAL_NOR_MspWait()
