Using watch-dog timer

This example  illustrates  how the watch-dog  timer should not be used. A command  used for resetting this timer is intentionally left out in the main program loop, thus enabling it to win the time battle and cause the microcontroller  to be reset. As a result, the microcontroller

will be reset all the time, which is reflected as PORTB LED blinking.

In order to make this example work properly, it is necessary to enable the watchdog timer by selecting the Watchdog Timer - Enabled option in mE programmer.
