  * @brief   FLASH HAL module driver.

  *          This file provides firmware functions to manage the following

  *          functionalities of the internal FLASH memory:

  *           + Program operations functions

  *           + Memory Control functions

  *           + Peripheral State functions

  *        

  @verbatim

  ==============================================================================

                        ##### 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 STM32L1xx 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

        (++) Program functions: Fast Word and Half Page(should be

        executed from internal SRAM).

      (#) DATA EEPROM Programming functions: this group includes all

          needed functions to erase and program the DATA EEPROM memory:

        (++) Lock and Unlock the DATA EEPROM interface.

        (++) Erase function: Erase Byte, erase HalfWord, erase Word, erase

             Double Word (should be executed from internal SRAM).

        (++) Program functions: Fast Program Byte, Fast Program Half-Word,

             FastProgramWord, Program Byte, Program Half-Word,

             Program Word and Program Double-Word (should be executed

             from internal SRAM).

      (#) 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

        (++) Set/Get the Read protection Level.

        (++) Set/Get the BOR level.

        (++) 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

    (#) FLASH Interface configuration functions: this group includes

      the management of following features:

      (++) Enable/Disable the RUN PowerDown mode.

      (++) Enable/Disable the SLEEP PowerDown mode.  

    (#) FLASH Peripheral State methods: this group includes

      the management of following features:

      (++) Wait for the FLASH operation

      (++)  Get the specific FLASH error flag

  [..] 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 64 bit Read Access.

      (+) Enable/Disable the Flash power-down

      (+) Enable/Disable the FLASH interrupts

      (+) Monitor the FLASH flags status

                 ##### Programming operation functions #####

  ===============================================================================  

     [..]

     This subsection provides a set of functions allowing to manage the FLASH

     program operations.

    [..] The FLASH Memory Programming functions, includes the following functions:

     (+) HAL_FLASH_Unlock(void);

     (+) HAL_FLASH_Lock(void);

     (+) HAL_FLASH_Program(uint32_t TypeProgram, uint32_t Address, uint32_t Data)

     (+) HAL_FLASH_Program_IT(uint32_t TypeProgram, uint32_t Address, uint32_t Data)

     [..] Any operation of erase or program should follow these steps:

     (#) Call the HAL_FLASH_Unlock() function to enable the flash control register and

         program memory access.

     (#) Call the desired function to erase page or program data.

     (#) Call the HAL_FLASH_Lock() to disable the flash program memory access

        (recommended to protect the FLASH memory against possible unwanted operation).

               ##### Option Bytes Programming functions #####

   ==============================================================================  

     [..] The FLASH_Option Bytes Programming_functions, includes the following functions:

     (+) HAL_FLASH_OB_Unlock(void);

     (+) HAL_FLASH_OB_Lock(void);

     (+) HAL_FLASH_OB_Launch(void);

     (+) HAL_FLASHEx_OBProgram(FLASH_OBProgramInitTypeDef *pOBInit);

     (+) HAL_FLASHEx_OBGetConfig(FLASH_OBProgramInitTypeDef *pOBInit);

     [..] Any operation of erase or program should follow these steps:

     (#) Call the HAL_FLASH_OB_Unlock() function to enable the Flash option control

         register access.

     (#) Call the following functions to program the desired option bytes.

         (++) HAL_FLASHEx_OBProgram(FLASH_OBProgramInitTypeDef *pOBInit);      

     (#) Once all needed option bytes to be programmed are correctly written, call the

         HAL_FLASH_OB_Launch(void) function to launch the Option Bytes programming process.

     (#) Call the HAL_FLASH_OB_Lock() to disable the Flash option control register access (recommended

         to protect the option Bytes against possible unwanted operations).

    [..] Proprietary code Read Out Protection (PcROP):    

    (#) The PcROP sector is selected by using the same option bytes as the Write

        protection. As a result, these 2 options are exclusive each other.

    (#) To activate PCROP mode for Flash sectors(s), you need to follow the sequence below:

        (++) Use this function HAL_FLASHEx_AdvOBProgram with PCROPState = OB_PCROP_STATE_ENABLE.
