Module on/off signal, pull up to power on, and pull
down to power off. In the power-off state, pull up
the FCP# for more than 1.2s. The module is

5.2.1. Power on/off
5.2.1.1. Power on
When the module power-on pin FCPO# (FULL_CARD_POWER_OFF#) is connected to an
external voltage of 3.3 V or 1.8 V, the module is powered on. When the AP (Application
Processor) controls the power-on of the module, it is recommended to use GPIO with the
reset status of low or internal pull-down.
