In Normal mode, writing 0xA5 to this register during the watchdog time-out period will clear the Watchdog Timer and the watchdog time-out period is restarted.

In Window mode, any writing attempt to this register before the time-out period started (i.e., during TOWDTW) will issue an immediate system Reset. Writing 0xA5 during the time-out period TOWDT will clear the Watchdog Timer and the complete time-out sequence (first TOWDTW then TOWDT) is restarted.

In both modes, writing any other value than 0xA5 will issue an immediate system Reset.
