Reference Design - ACOK Usage

In the shcematic, I see signal called ACOK which is input to U79, EFM8SB10F8G, and is coming from pin 6 of J508 (Force Recovery, Reset & Power Header), and has a pull-down on-board.

The only information I found on this is that it is 'AC (USB Type C or DC Jack) power OK ’
(JETSON XAVIER | DEVELOPER KIT CARRIER BOARD | SPECIFICATION | 20180809),

As the board works fine without this connection, I assume that user can connect this pin to high-level and this will disable power-up or cause power-off.

Am I correct? If not, what’s the usage for this signal?

Thanks.

Sorry,

Found that this can serve as Auto power-on,

Assume that once this is pulled-high, the EMF8 will power-up the system without waiting for the power-switch event.
