5.3.1. Shutdown by Software Command
The LE910Cx module can be shut down by a software command.
When a shutdown command is sent, LE910Cx goes into the Finalization state and at the
end of the finalization process shuts down PWRMON.
The duration of the Finalization state can differ according to the current situation of the
module, so a value cannot be defined.
Usually, it will take more than 10 seconds from sending a shutdown command until
reaching a complete shutdown. The DTE host should monitor the status of PWRMON to
observe the actual power-off.

NOTE:
To check whether the device has powered off, monitor the PWRMON
hardware line. When PWRMON goes low, the device has powered off.
