●About the Power On Reset

Power on reset is not mandatory for this device.

(The PD pin should be set to high level when power on reset procedure is not used.)

Datasheet

Figure 10. Terminal connection when power on reset is not used.

However, Power on reset procedure is strongly recommend for internal logic initialization by following two methods.

①The method of using CR circuit.

②The method of using external specific IC.

It is recommend to do enough examination for target application.
