Note: The resistance and capacitance for reset circuit should be designed in such a way as to ensure that the VDD is
stable and remains within a valid operating voltage range before bringing RES to high.
²*² Make the length of the wiring, which is connected to the RES pin as short as possible, to avoid noise
interference.
