 ==============================================================================
                   ##### Flash Extended features #####
  ==============================================================================
           
  [..] Comparing to other previous devices, the FLASH interface for STM32L4xx 
       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 STM32L4xx 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 page, 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 function: Use HAL_FLASHEx_OBProgram() to :
        (++) Set/Reset the write protection
        (++) Set the Read protection Level
        (++) Program the user Option Bytes
        (++) Configure the PCROP protection
        
      (#) Get Option Bytes Configuration function: Use HAL_FLASHEx_OBGetConfig() to :
        (++) Get the value of a write protection area
        (++) Know if the read protection is activated
        (++) Get the value of the user Option Bytes
        (++) Get the value of a PCROP area
