@par Example Description 

This example shows how to modify CortexM3 Thread mode privilege access and stack.
CortexM3 Thread mode is entered on Reset, and can be entered as a result of an
exception return.  

The associated program is used to:

1. Switch the Thread mode stack from Main stack to Process stack

2. Switch the Thread mode from Privileged to Unprivileged

3. Switch the Thread mode from Unprivileged back to Privileged

To monitor the stack used and the privileged or unprivileged access level of code
in Thread mode, a set of variables is available within the program. It is also
possible to use the 'Cortex register' window of the debugger.

@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   
- 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.
