@par Example Description 

This example provides a description of how to enable and disable the write protection
for the STM32F10x FLASH:

- Enable Write protection: 
To enable the Write Protection, uncomment the line "#define WriteProtection_Enable"
in main.c file.
  
To protect a set of pages, the user has to call the function FLASH_EnableWriteProtection.
The parameter of this function will define the number of pages to be protected.
To load the new option byte values, a system Reset is necessary, for this, the
function NVIC_SystemReset() is used.
 
- Disable Write protection:
To disable the Write Protection, uncomment the line "#define WriteProtection_Disable"
in main.c file.

To disable the write protection of the STM32F10x Flash, an erase of the Option 
Bytes is necessary. This operation is done by the function FLASH_EraseOptionBytes.
To load the new option byte values, a system Reset is necessary, for this, the
function NVIC_SystemReset() is used.

If the desired pages are not write protected, an erase and a write operation are
performed.

@par Hardware and Software environment 

  - This example runs on STM32F10x High-Density, STM32F10x Medium-Density and
    STM32F10x Low-Density Devices.
  
  - This example has been tested with STMicroelectronics STM3210E-EVAL (STM32F10x 
    High-Density) and STM3210B-EVAL (STM32F10x Medium-Density) evaluation boards 
    and can be easily tailored to any other supported device and development 
    board.
    To select the STMicroelectronics evaluation board used to run the example, 
    uncomment the corresponding line in platform_config.h file.    
  
@par How to use it ? 

In order to make the program work, you must do the following:
- Create a project and setup all project configuration
- Add the required Library files:
  - stm32F10x_flash.c
  - system_stm32f10x.c 
   
- Edit stm32f10x.h file to select the device you are working on.
  
@b Tip: You can tailor the provided project template to run this example, for 
        more details please refer to "stm32f10x_stdperiph_lib_um.chm" user 
        manual; select "Peripheral Examples" then follow the instructions 
        provided in "How to proceed" section.   
- Link all compiled files and load your image into target memory
- Run the example

@note
 - Low-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 16 and 32 Kbytes.
 - Medium-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 32 and 128 Kbytes.
 - High-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 256 and 512 Kbytes.
