@par Example Description

How to enter the STOP_MAINREGU mode.

After start-up LED2 is toggling during 5 seconds, then the system automatically 
enter in STOP_MAINREGU mode (Final state).

LED2 is used to monitor the system state as follows:
 - LED2 toggling : system in RUN mode
 - LED2 off : system in STOP_MAINREGU mode

@note To measure the current consumption in STOP_MAINREGU mode, remove JP6 jumper 
      and connect an ampere meter to JP6 to measure IDD current.     

@note This example can not be used in DEBUG mode due to the fact 
      that the Cortex-M3 core is no longer clocked during low power mode 
      so debugging features are disabled.

@par Hardware and Software environment

  - This example runs on STM32F103xB devices.
    
  - This example has been tested with STMicroelectronics STM32F103RB-Nucleo
    board and can be easily tailored to any other supported device
    and development board.

  - STM32F103RB-Nucleo Set-up
    - LED2 connected to PA.05 pin

@par How to use it ? 

In order to make the program work, you must do the following :
 - Open your preferred toolchain
 - Rebuild all files and load your image into target memory
 - Run the example
