Power_On_Off
MU736 is powered directly to battery
For use case MU736 is connected directly to battery, such as tablet platforms,
Power_On_Off pin should be controlled by a GPIO from host to control MU736 power
On/Off.
It is critical to make sure the module is safely powered off when the Tablet SoC is shut
off. There will be current leakage if the module is not powered off properly. So It is
important to keep Power_On_Off pin logic low for more than 500 ms to power off the
module.
