Figure 13:.Available trigger sources for watchdog timer overflow
The watchdog timer overflow interval can be programmed through Windows
API. After enabling the watchdog timer, users must periodically reset the timer
by software command. If the timer is not being reset within the specified interval,
the switch module will generate an overflow signal and set the relay pattern to
the one specified by users.
This function is disabled by default. For more information, please refer to the
software programming users’ guide.
