 ==Summary==
-The <code>watchdog</code> C example project demonstrates how to use the '''watchdog timer'''. The '''watchdog timer''' is there to help you ensure that your program won't get stuck while executing your code. It provides a way to set the outputs of a device into known safe-states in the event of a system fault or failure.

-EMAC provides examples of how to enable, disable, activate, configure and interrupt the <code>watchdog</code> hardware circuit. To use <code>watchdog</code> peripheral in Linux you will need a <code>watchdog</code> driver, and a <code>watchdog</code> device file. Device file is a special kind of file to mark the device node in your root filesystem. Normally it's called <code>/dev/watchdog</code> .
