WDOG_Feed()

Feeds the watchdog timer and saves your code from unexpected reboot. In most cases there is no need to feed watchdog. It is fed by main logic automatically, buf If you need to process some hard greedy job that lasts more the 500 milliseconds it's highly recommend to feed watchdog during processing. Itstead of WDOG_Feed you can use delay(1); for the same result.
