Detailed Description

This file includes a standard driver for the PC28F128M29EWLA NOR flash memory device mounted on STM32F769I-EVAL evaluation boards.

  How To use this driver:
  -----------------------
   - This driver is used to drive the PC28F128M29EWLA NOR flash external memory mounted
     on STM32F769I-EVAL evaluation board.
   - This driver does not need a specific component driver for the NOR device
     to be included with.

  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.
