When the hold time of ON/OFF# reaches above 2 seconds, HE863
Family 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 from the
situation in which the HE863 Family is so it cannot be fixed
definitely.
Normally it will take above 10 seconds later from releasing
ON/OFF# 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 it can be considered
the device has powered off.
