How to set Watch Dog Timer in Intel Galileo

I am working on Intel Galileo (Linux running on it). Now I want to set a watch dog timer to reset my sketch if some error is acknowledged or my sketch crashes due to some reason.

I have gone through Intel Galileo datasheet but didn't find anything regarding watch dog timer.

So, I tried quark x1000 datasheet but couldn't make much out of it.

I am not able to understand how watch dog timer is initialized on Intel Galileo.
