Hi,

In datasheet it mentions that 3ms delay is required after all power supply get stable, here would like to know the start/end point for the 3ms delay, thanks.

    Hello Andy,

        Power supplies need to settle before before NRESET release happens, This is important requirement, 3msec is not a hard requirement but approximate guidance number, typically due to decoupling caps and output impedance of the power management network might affect the settling behavior of the power supplies.  But care must be taken to release the NRESET when power supplies are stable. 

    Thanks and regards,
