/* File Info : -----------------------------------------------------------------
User NOTES
1. How To use this driver:
--------------------------
- This driver is used to drive the M29W128GL NOR flash external memory mounted
on STM32469I-EVAL evaluation board.
- This driver does not need a specific component driver for the NOR device
to be included with.
2. Driver description:
---------------------
+ Initialization steps:
o Initialize the NOR external memory using the BSP_NOR_Init() function. This
function includes the MSP layer hardware resources initialization and the
FMC controller configuration to interface with the external NOR memory.
+ NOR flash operations
o NOR external memory can be accessed with read/write operations once it is
initialized.
Read/write operation can be performed with AHB access using the functions
BSP_NOR_ReadData()/BSP_NOR_WriteData(). The BSP_NOR_WriteData() performs write operation
of an amount of data by unit (halfword). You can also perform a program data
operation of an amount of data using the function BSP_NOR_ProgramData().
o The function BSP_NOR_Read_ID() returns the chip IDs stored in the structure
"NOR_IDTypeDef". (see the NOR IDs in the memory data sheet)
o Perform erase block operation using the function BSP_NOR_Erase_Block() and by
specifying the block address. You can perform an erase operation of the whole
chip by calling the function BSP_NOR_Erase_Chip().
o After other operations, the function BSP_NOR_ReturnToReadMode() allows the NOR
flash to return to read mode to perform read operations on it.
