  ==============================================================================
                   ##### Flash Extension features #####
  ==============================================================================

  [..] Comparing to other previous devices, the FLASH interface for STM32F427xx/437xx and
       STM32F429xx/439xx devices contains the following additional features

       (+) Capacity up to 2 Mbyte with dual bank architecture supporting read-while-write
           capability (RWW)
       (+) Dual bank memory organization
       (+) PCROP protection for all banks

                      ##### How to use this driver #####
  ==============================================================================
  [..] This driver provides functions to configure and program the FLASH memory
       of all STM32F427xx/437xx, STM32F429xx/439xx, STM32F469xx/479xx and STM32F446xx
       devices. It includes
      (#) FLASH Memory Erase functions:
           (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
                HAL_FLASH_Lock() functions
           (++) Erase function: Erase sector, erase all sectors
           (++) There are two modes of erase :
             (+++) Polling Mode using HAL_FLASHEx_Erase()
             (+++) Interrupt Mode using HAL_FLASHEx_Erase_IT()

      (#) Option Bytes Programming functions: Use HAL_FLASHEx_OBProgram() to :
           (++) Set/Reset the write protection
           (++) Set the Read protection Level
           (++) Set the BOR level
           (++) Program the user Option Bytes
      (#) Advanced Option Bytes Programming functions: Use HAL_FLASHEx_AdvOBProgram() to :
       (++) Extended space (bank 2) erase function
       (++) Full FLASH space (2 Mo) erase (bank 1 and bank 2)
       (++) Dual Boot activation
       (++) Write protection configuration for bank 2
       (++) PCROP protection configuration and control for both banks
