AM5728: When the RSTOUTn pin of the AM5728 is output low.

Part Number: AM5728

Hi,

What are the conditions under which the RSTOUTn pin of the AM5728 is output low? I understand that RSTOUTn "L" is output low during a Warm Reset (only the software is restarted without turning off the power completely).
I would like to know if the Warm Reset occurs at a given timing. We have a problem that RSTOUTn is output to “L” at an unintended timing.

Thanks,

Eevee

    RSTOUTn is asserted (low) in response to any global reset condition within the processor.  It could be result from an external reset (cold PORz or warm RESETn) or an internal reset event.  Note RSTOUTn is only valid after its IO rail (VDDSHV3) is valid.
