To ensure the reliability in an unmanned or standalone system, the Watchdog Timer (WDT) onboard HS-2601A is designed with pure hardware that does not need the arithmetical functions of a real-time clock chip. If any program causes unexpected halts to the system, the onboard Watchdog Timer (WDT) will automatically reset the CPU or generate an interrupt to resolve such condition.
