+Example description
+===================
+This example shows how to update at regulate period the WWDG counter using the
+Early Wakeup interrupt (EWI).
+
+The WWDG timeout is set to 262 ms, the refresh window is set to 65 and the EWI is
+enabled. When the WWDG counter reaches 64, the EWI is generated. In the WWDG ISR,
+the counter is refreshed to prevent a WWDG reset and a specific GPIO pin is toggled.
+
+An EXTI Line is connected to a GPIO pin, and configured to generate an interrupt
+on the falling edge of the signal.
+In the NVIC (nested vectored interrupt controller), the EXTI Line interrupt
+vector is enabled with a priority equal to 0 and the WWDG interrupt vector is
+enabled with a priority equal to 1 (EXTI IT > WWDG IT).
+
+The EXTI Line is used to simulate a software failure: once the EXTI Line event occurs
+(by pressing the Key push-button on the STM3210B-EVAL board), the corresponding
+interrupt is served. In the ISR, the GPIO pin is reset and the EXTI Line pending 
+bit is not cleared. So the CPU executes the EXTI Line ISR indefinitely and the 
+WWDG ISR is never executed (the WWDG counter is not updated).
+As a result, when the WWDG counter falls to 63, the WWDG reset occurs.
+If the WWDG reset is generated, after the system resumes from reset, an other GPIO
+is set.
+
+If the EXTI Line event does not occur, the WWDG counter is indefinitely refreshed
+in the WWDG ISR, and there is no WWDG reset.
+
+In this example the system is clocked by HSE, the high-speed external clock (8 MHz).

+Hardware environment
+====================
+This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation
+boards and can be easily tailored to any other hardware.
+To select the STMicroelectronics evaluation board used to run the example, uncomment
+the corresponding line in platform_config.h file.
+
+ + STM3210B-EVAL 
+    - Use LD1 and LD2 leds connected respectively to PC.06 and PC.07 pins, and the
+      KEY push button connected to PB.09 pin.
+ 
+ + STM3210E-EVAL
+    - Use LD1 and LD2 leds connected respectively to PF.06 and PF.07 pins, and the
+      KEY push button connected to PG.08 pin.
+
+    
+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_gpio.c
+  + stm32f10x_rcc.c
+  + stm32f10x_nvic.c
+  + stm32f10x_wwdg.c
+  + stm32f10x_flash.c
+  + stm32f10x_exti.c  
+
+- Link all compiled files and load your image into target memory
+- Run the example in standalone mode (without debugger connection)
