Shutdown process
When the module is in a normal startup state, during the process of shutting down the module by controlling
PWRKEY_N, the module will first perform the reset process, and finally enter the shutdown state. It is
recommended that before shutdown, the MCU completes the data communication operation with the UART,
USB and other interfaces of the module, and then performs the shutdown operation.
If the design of automatic startup upon power-on is adopted, shutdown can be performed only through power-
down.
Two methods are available to shut down the module: hard shutdown and soft shutdown.

Shut down the module through hardware can be performed by controlling the PWRKEY_N pin.
