Shutdown by Software Command
LE920 can be shut down by a software command.
When a shut down command is sent, LE920 goes into the finalization state and finally will
shut down PWRMON at the end of this state.
The period of the finalization state can differ according to the situation in which the LE920 is
so it cannot be fixed definitely.
Normally it will be above 10 seconds later from sending a shut down command and DTE
should monitor the status of PWRMON to see the actual power off.
TIP:
To check if the device has powered off, hardware line PWRMON must be monitored. When
PWRMON goes low, the device has powered off.
