• All power shut except for the RTC.
• No Wake events occur, because the system does not have
any power.
This state occurs if user removes the batteries, turns off a
mechanical switch, or if the system power supply is at a level
that is insufficient to power the waking logic.
When system power returns, transition depends on the state
When system power returns, transition depends on the state
