                       ##### How to use this driver #####
===============================================================================
   [..]                             
     This driver provides functions to configure and program the FLASH memory 
     of all STM32F4xx devices. These functions are split in 4 groups:
  
     (#) FLASH Interface configuration functions: this group includes the
         management of the following features:
       (++) Set the latency
       (++) Enable/Disable the prefetch buffer
       (++) Enable/Disable the Instruction cache and the Data cache
       (++) Reset the Instruction cache and the Data cache
   
     (#) FLASH Memory Programming functions: this group includes all needed
         functions to erase and program the main memory:
       (++) Lock and Unlock the FLASH interface
       (++) Erase function: Erase sector, erase all sectors
       (++) Program functions: byte, half word, word and double word
   
     (#) Option Bytes Programming functions: this group includes all needed
         functions to manage the Option Bytes:
       (++) Set/Reset the write protection
       (++) Set the Read protection Level
       (++) Set the BOR level
       (++) Program the user Option Bytes
       (++) Launch the Option Bytes loader
   
     (#) Interrupts and flags management functions: this group 
         includes all needed functions to:
       (++) Enable/Disable the FLASH interrupt sources
       (++) Get flags status
       (++) Clear flags
       (++) Get FLASH operation status
       (++) Wait for last FLASH operation
