The switch-over mode time enables the synchronous operation of microcontroller and watchdog. When the power-up reset time has elapsed, the watchdog has to be switched to monitoring mode by the microcontroller by a "low" signal transmitted to the mode pin (pin 12) within the time-out period, ti. If the low signal does not occur within ti, (see Fig- ure 4) the watchdog generates a reset pulse, t6, and the time, ti, starts again. Microcontroller and watchdog are synchronized with the switchover mode time, ti, each time a reset pulse is generated.
