| mbed_official | 87:085cde657901 | 13 | ##### How to use this driver ##### |
| mbed_official | 87:085cde657901 | 14 | ============================================================================== |
| mbed_official | 87:085cde657901 | 15 | [..] |
| mbed_official | 87:085cde657901 | 16 | This driver is a generic layered driver which contains a set of APIs used to |
| mbed_official | 87:085cde657901 | 17 | control NOR flash memories. It uses the FMC/FSMC layer functions to interface |
| mbed_official | 87:085cde657901 | 18 | with NOR devices. This driver is used as follows: |
| mbed_official | 87:085cde657901 | 19 | |
| mbed_official | 87:085cde657901 | 20 | (+) NOR flash memory configuration sequence using the function HAL_NOR_Init() |
| mbed_official | 87:085cde657901 | 21 | with control and timing parameters for both normal and extended mode. |
| mbed_official | 87:085cde657901 | 22 | |
| mbed_official | 87:085cde657901 | 23 | (+) Read NOR flash memory manufacturer code and device IDs using the function |
| mbed_official | 87:085cde657901 | 24 | HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef |
| mbed_official | 87:085cde657901 | 25 | structure declared by the function caller. |
| mbed_official | 87:085cde657901 | 26 | |
| mbed_official | 87:085cde657901 | 27 | (+) Access NOR flash memory by read/write data unit operations using the functions |
| mbed_official | 87:085cde657901 | 28 | HAL_NOR_Read(), HAL_NOR_Program(). |
| mbed_official | 87:085cde657901 | 29 | |
| mbed_official | 87:085cde657901 | 30 | (+) Perform NOR flash erase block/chip operations using the functions |
| mbed_official | 87:085cde657901 | 31 | HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip(). |
| mbed_official | 87:085cde657901 | 32 | |
| mbed_official | 87:085cde657901 | 33 | (+) Read the NOR flash CFI (common flash interface) IDs using the function |
| mbed_official | 87:085cde657901 | 34 | HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef |
| mbed_official | 87:085cde657901 | 35 | structure declared by the function caller. |
| mbed_official | 87:085cde657901 | 36 | |
| mbed_official | 87:085cde657901 | 37 | (+) You can also control the NOR device by calling the control APIs HAL_NOR_WriteOperation_Enable()/ |
| mbed_official | 87:085cde657901 | 38 | HAL_NOR_WriteOperation_Disable() to respectively enable/disable the NOR write operation |
| mbed_official | 87:085cde657901 | 39 | |
| mbed_official | 87:085cde657901 | 40 | (+) You can monitor the NOR device HAL state by calling the function |
| mbed_official | 87:085cde657901 | 41 | HAL_NOR_GetState() |
| mbed_official | 87:085cde657901 | 42 | [..] |
| mbed_official | 87:085cde657901 | 43 | (@) This driver is a set of generic APIs which handle standard NOR flash operations. |
| mbed_official | 87:085cde657901 | 44 | If a NOR flash device contains different operations and/or implementations, |
| mbed_official | 87:085cde657901 | 45 | it should be implemented separately. |
