How to control PMIC in Low power mode on i.MX8 mini EVK boad

Hi all.

I am trying to do a personal development with an i.MX8 mini EVK board.
My question is whether the power supplied to the MCU in Low power mode (STOP, WAIT , Deep Sleep) should be controlled by the PMIC? If there is a document that describes what voltage should be applied to which pin in each state, please introduce it to me.
From reading the reference manual it looks like I'm fiddling with the Power gating controller(PGC)  and shutting off the voltage inside the MCU.

Thank you.

Hi all.

I know from this document which power line to turn on and off in which state.

But I still don't know how to transition from each state.
