How to program the RockpiN10's MCU?

Hi ,
I want to set the RockPiN10 into standby mode and wake it up with some remote command. As I know on other SOC platform, there’s a “standby MCU” to control the SOC’s power status. How to do it on RockPiN10?
From, I can find a very simple M0 MCU code, and don’t know how to control main cpu. Is there any more information about this?

This guide may help you.

Hi, Stephen,
From the document, the MCU’s clock source and reset is controled by Main cpu. That means the MCU run after main cpu start up, so it can not control the power of main cpu.
If I need save power in standy mode, how to do it? Can the system be managed by ACPI by MCU?
