@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 Connectivity line, High-Density, Medium-Density, 
    Medium-Density Value line, Low-Density and Low-Density Value line Devices.
  
  - This example has been tested with STMicroelectronics STM32100B-EVAL 
    (STM32F10x Medium-Density Value line), STM3210C-EVAL (STM32F10x Connectivity 
    line), 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.  
  
@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 (under Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x) 
   
- 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 Value line devices are STM32F100xx microcontrollers where the 
   Flash memory density ranges between 16 and 32 Kbytes.
 - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx 
   microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes.
 - Medium-density Value line devices are STM32F100xx microcontrollers where
   the Flash memory density ranges between 64 and 128 Kbytes.  
 - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx 
   microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes.
 - High-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 256 and 512 Kbytes.
 - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
