Example description
===================
This example shows how to write/read data to/from Backup data registers and 
demonstrates the Tamper detection feature.

The associated firmware performs the following:
1. It configures the ANTI_TAMP pin to be active low, and enables the Tamper interrupt.
2. It writes the data to all Backup data registers, then check whether the data were
correctly written. If yes, the LED connected to PC.06 turns on, otherwise the LED
connected to PC.07 turns on.
3. On applying a low level on the ANTI_TAMP pin (PC.13), the Backup data registers
are reset and the Tamper interrupt is generated. The corresponding ISR then checks
whether the Backup data registers are cleared. If yes, the LED connected to PC.08
turns on, otherwise the LED connected to PC.09 is turns on.

Hardware environment
====================
 - Connect four leds to pins PC.06, PC.07, PC.08 and PC.09 (respectively LD1, LD2,
   LD3 and LD4 on STM3210B-EVAL board).
 - Connect a push-button to pin PC.13 (ANTI_TAMP) (Tamper push-button on
   STM3210B-EVAL board).

    
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_lib.c
  + stm32f10x_pwr.c
  + stm32f10x_bkp.c
  + stm32f10x_gpio.c
  + stm32f10x_rcc.c
  + stm32f10x_nvic.c
  + stm32f10x_flash.c
  
- Link all compiled files and load your image into either RAM or FLASH
- Run the example
