5.11. Reset Function

The GPL10B can be reset by setting the RESET pin to ground

voltage and its operation starts when this pin is set to power

voltage.

Also an automatic reset function (internal reset function)

operates when power is turned on.

5.12. Watchdog Function

The GPL10B provides a watchdog timer.

The watchdog timer

must be reset when 2Hz wake-up by writing $0F; otherwise, it will

reset the system.
