POWER_ON signal.
The POWER_ON is low in the beginning. Once there gives POWER_ON a high RISE EDGE
more than 1.2V, the ZM8620 MODULE will be Power-on. That is the Power-on flow.
If there gives POWER_ON a low LEVEL, the POWER_ON signal becomes low; the ZM8620
MODULE will be Power-off. That is the Power-off flow.
