本例示范了如何修改Cortex-M3内核在Thread模式下，如何修改：
1. 将默认堆栈由main stack改为Process stack
2. 将权限由优先（Privileged）改为非优先（Unprivileged or User）
3. 将权限由非优先（Unprivileged or User）改为优先（Privileged）

在Thread模式下，由一系列变量可以指示当前使用的堆栈，和权限是privileged还是unprivileged。也可以在debugger里使用'Cortex register' 窗口。

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.


Directory contents
==================
stm32f10x_conf.h  Library Configuration file
stm32f10x_it.c    Interrupt handlers
stm32f10x_it.h    Header for stm32f10x_it.c
main.c            Main program


Hardware environment
====================

    
How to use it
=============
In order to make the program work, you must do the following :
- Create a project and setup all your toolchain's start-up files
- Compile the directory content files and required Library files :
  + stm32f10x_nvic.c
  + stm32f10x_rcc.c
  + stm32f10x_lib.c
  + stm32f10x_flash.c           
    
- Link all compiled files and load your image into either RAM or FLASH
- Run the example
