Jetson Orion NX

We are using Jetson Orion NX module for our project, in this module what is the purpose of Power EN pin and how much delay we need to give in Power enable pin with respect to VIN.
What kind of circuitry/configuration we need to follow to achieve the required delay on this pin.

Please read and refer to the Orin NX/Nano Design Guide doc in DLC for such questions.
