WATCHDOG TIMER (WDT)
The watchdog timer is a free running timer equipped with a non-maskable interrupt function to prevent
program hang-up or deadlock. When an error of the program is detected, the overflow interrupt (INTWDT) of
the watchdog timer occurs and the watchdog timer output pin (WDTO) goes low. By connecting this output pin
to the RESET pin, any malfunctioning of the application system due to program error can be prevented.
