|

* This file provides a generic firmware to drive NOR memories mounted

==============================================================================
|
||
|
##### 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
