6. Function and Features
6.1. Power on/off
6.1.1. Power on
The module is powered on as input triggered by VBAT.
When the module is powered, the PMU_SHUTDOWN pin is PU internally.
*When the PMU_SHUTDOWN pin is connected to an external switch without being connected to the
host, the PMU_SHUTDOWN pin is PU internally, so not connecting external PU.
HOST does not need to input a signal to the PMU_SHUTDOWN pin, PMU_SHUTDOWN pin should be
opened.
