As with all of our host chargers, the watchdog timer is used to confirm that a host is present and presumably monitoring charge operation for safety. If it expires, the registers return to default settings, which, we predict, will provide a safer charge configuration (lower input current limit, lower charge current, etc). Disabling the watchdog timer is acceptable.
