Power Fail Resume Type
Always ON

Last State
Determine the System Behavior after a power failure event.
In case the option is
“
Always ON
”
, the board will start every time the power supply is present.
When the option is
“
Always OFF
”
, the board will not start automatically when the power supply returns.
Finally, if this option is set to
“
Last State
”
, the board will remember the state it had when the power supply
went down: so, if the board was on, it will start again when the power returns, and will remain off if the
board was in this state when the power went down.
