AM5728: Power-up sequencing

Part Number: AM5728
Other Parts Discussed in Thread: LMK04806

Hello,

We're now using AM5728 to desigh a Minimum System and I have several questions about the Power-up Sequencing:

1)According to the datasheet,after powering up the "vddshav8", clock "xi-osC0" should be generated. But now the clock we generated will have an abnormal waveform before it is stable(see the figures below), will this waveform affect the following sequencing?

2.I'm not sure if it is because of the abnormal waveform I mentioned above, I can not get high outputs for the signals of "rtc_porz,porz,rstoutn". What can I do to get the correct outputs?

3.Which signals can be used for judging that the minimum system for AM5728 is operating?

Looking forward to your reply!

Best regards,
