-Example description
-===================
-This example shows how to reload at regulate period the IWDG counter using the
-SysTick interrupt. The IWDG timeout is set to 280 ms (the timeout may varies due
-to LSI frequency dispersion).
-
-SysTick is configured to generate an interrupt every 250 ms. In the SysTick interrupt
-service routine (ISR), the IWDG counter is reloaded to prevent an IWDG reset, and
-a specific GPIO pin is toggled.
-An EXTI is connected to a specific GPIO pin and configured to generate an interrupt
-on its falling edge.
-In the NVIC, this EXTI line corresspondant interrupt vector is enabled with a
-priority equal to 0, and the SysTick interrupt vector priority is set to 1
-(EXTI IT > SysTick IT).
-
-The EXTI Line is used to simulate a software failure: when the EXTI Line event is
-triggered (by pressing the Key push-button on the board), the corresponding interrupt
-is served. In the ISR, the GPIO pin turns off and the EXTI line pending bit is
-not cleared. So the CPU executes the EXTI line ISR indefinitely and the SysTick
-ISR is never entered (IWDG counter not reloaded).
-As a result, when the IWDG counter reaches 00h, the IWDG generates a reset.
-If the IWDG reset is generated, an other specific GPIO pin is turned on after
-the system resumes operation.
-
-If the EXTI Line event does not occur, the IWDG counter is indefinitely reloaded in
-the SysTick ISR, which prevents any IWDG reset.
-
-In this example the system is clocked by the high-speed external (HSE) 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_iwdg.c
- + stm32f10x_flash.c
- + stm32f10x_exti.c
- + stm32f10x_systick.c
-
-- Link all compiled files and load your image into target memory
-- Run the example in standalone mode (without debugger connection)
