Overview
The WDOG Example project is to demonstrate usage of the KSDK wdog driver. In this example,implemented to test the wdog. Please notice that because WDOG control registers are write-once only. And for the field WDT, once software performs a write "1" operation to this bit, it can not be reset/cleared until the next POR, this bit does not get reset/ cleared due to any system reset. So the WDOG_Init function can be called only once after power reset when WDT set, and the WDOG_Disable function can be called only once after reset.

Prepare the Demo
- Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
- Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
- Download the program to the target board.
- Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
These instructions are displayed/shown on the terminal window:
******** System Start ********
System reset by: Power On Reset!
- 1.Testing System reset by software trigger.
******** System Start ********
System reset by: Software Reset!
- 2.Testing system reset by WDOG timeout.
--- wdog Init done---
******** System Start ********
System reset by: Time Out Reset!
- 3.Test the WDOG refresh function by using interrupt.
--- wdog Init done---
WDOG has be refreshed!
WDOG has be refreshed!
WDOG has be refreshed!

Note:
To debug in qspiflash, following steps are needed:
1. Select the flash target and compile.
2. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
3. Start debugging in IDE.
- Keil: Click "Download (F8)" to program the image to qspiflash first then clicking "Start/Stop Debug Session (Ctrl+F5)" to start debugging.
