  ==============================================================================
                        ##### FLASH peripheral features #####
  ==============================================================================
  [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses 
       to the Flash memory. It implements the erase and program Flash memory operations 
       and the read and write protection mechanisms.

  [..] The Flash memory interface accelerates code execution with a system of instruction
      prefetch. 

  [..] The FLASH main features are:
      (+) Flash memory read operations
      (+) Flash memory program/erase operations
      (+) Read / write protections
      (+) Prefetch on I-Code
      (+) Option Bytes programming


                     ##### How to use this driver #####
  ==============================================================================
  [..]                             
      This driver provides functions and macros to configure and program the FLASH 
      memory of all STM32F1xx devices.
    
      (#) FLASH Memory I/O Programming functions: this group includes all needed
          functions to erase and program the main memory:
        (++) Lock and Unlock the FLASH interface
        (++) Erase function: Erase page, erase all pages
        (++) Program functions: half word, word and doubleword
    
      (#) FLASH Option Bytes Programming functions: this group includes all needed
          functions to manage the Option Bytes:
        (++) Lock and Unlock the Option Bytes
        (++) Set/Reset the write protection
        (++) Set the Read protection Level
        (++) Program the user Option Bytes
        (++) Launch the Option Bytes loader
        (++) Erase Option Bytes
        (++) Program the data Option Bytes
        (++) Get the Write protection.
        (++) Get the user option bytes.
    
      (#) Interrupts and flags management functions : this group 
          includes all needed functions to:
        (++) Handle FLASH interrupts
        (++) Wait for last FLASH operation according to its status
        (++) Get error flag status           

  [..] In addition to these function, this driver includes a set of macros allowing
       to handle the following operations:
      
      (+) Set/Get the latency
      (+) Enable/Disable the prefetch buffer
      (+) Enable/Disable the half cycle access
      (+) Enable/Disable the FLASH interrupts
      (+) Monitor the FLASH flags status
