24.4.2. Selecting the Output Response Mode

The watchdog timers have two output response modes. To select the desired mode, perform one of the following actions:
  • To generate a system reset request when a timeout occurs, write 0 to the output response mode bit (rmod) of the watchdog timer control register (wdt_cr).
  • To generate an interrupt and restart the timer when a timeout occurs, write 1 to the rmod field of the wdt_cr register.

If a restart occurs at the same time the watchdog counter reaches zero, a system reset is not generated. †
