AM623: About AM623 reset

?? ?
Prodigy 20 points
Part Number: AM623

Tool/software:

am623 includes three external reset input pins: MCU domain cold reset (MCU_PORz), MCU domain hot reset (MCU_RESETz) and master domain hot reset request (RESET_REQz).
And three reset status output pins: MCU domain hot reset status (MCU_RESETSTATz), master domain POR cold reset status (PORz_OUT) and master domain hot reset status (RESETSTATz).

① I looked at the power-on timing diagrams of the demo board and pmic. After power-on, MCU_PORz is set high. I want to ask if the M4F core of AM623 manages the power reset of the entire am623, and what is the positioning and function of M4F in AM623

② Do the two reset inputs MCU_RESETZ and RESET_REQZ have reset timing requirements when powering on? I didn't see it in the datasheet.

③ Are there timing instructions for the output of the three reset output pins? For example, after the system is normal, these three outputs should have a sequence.

④Where to find the reset tree？
