mbed_official 87:085cde657901 12 ==============================================================================
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.
