*The oscillation stabilizing time is a period until the oscillation becomes stable after VDD becomes higher than minimum
operating voltage. (Refer to Figure4)

(Notes) Since the circuit pattern affects the oscillation frequency, place the oscillation-related parts as close to the
oscillation pins as possible with the shortest possible pattern length.
