12 | ============================================================================== |
||
13 | ##### How to use this driver ##### |
||
14 | ============================================================================== |
||
15 | [..] |
||
16 | This driver is a generic layered driver which contains a set of APIs used to |
||
17 | control NOR flash memories. It uses the FSMC layer functions to interface |
||
18 | with NOR devices. This driver is used as follows: |
||
19 | |||
20 | (+) NOR flash memory configuration sequence using the function HAL_NOR_Init() |
||
21 | with control and timing parameters for both normal and extended mode. |
||
22 | |||
23 | (+) Read NOR flash memory manufacturer code and device IDs using the function |
||
24 | HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef |
||
25 | structure declared by the function caller. |
||
26 | |||
27 | (+) Access NOR flash memory by read/write data unit operations using the functions |
||
28 | HAL_NOR_Read(), HAL_NOR_Program(). |
||
29 | |||
30 | (+) Perform NOR flash erase block/chip operations using the functions |
||
31 | HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip(). |
||
32 | |||
33 | (+) Read the NOR flash CFI (common flash interface) IDs using the function |
||
34 | HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef |
||
35 | structure declared by the function caller. |
||
36 | |||
37 | (+) You can also control the NOR device by calling the control APIs HAL_NOR_WriteOperation_Enable()/ |
||
38 | HAL_NOR_WriteOperation_Disable() to respectively enable/disable the NOR write operation |
||
39 | |||
40 | (+) You can monitor the NOR device HAL state by calling the function |
||
41 | HAL_NOR_GetState() |
||
42 | [..] |
||
43 | (@) This driver is a set of generic APIs which handle standard NOR flash operations. |
||
44 | If a NOR flash device contains different operations and/or implementations, |
||
45 | it should be implemented separately. |
||
46 | |||
47 | *** NOR HAL driver macros list *** |
||
48 | ============================================= |
||
49 | [..] |
||
50 | Below the list of most used macros in NOR HAL driver. |
||
51 | |||
52 | (+) NOR_WRITE : NOR memory write data to specified address |
