AM5K2E02: Power down sequence

Part Number:AM5K2E02

Hi,

We are working on a prototype board with a AM5K2E02 processor. Our current power down sequence is to power down all rails simultaneously when input power is removed. 

We have measured the rails as they collapse and noticed that CVDD1 is greater than CVDD for roughly 2ms before it falls below CVDD. 

Is this likely to affect long term reliability of the processor?   

The other rails seem fine, but are there any others we should pay special attention to?

I've attached a screen shot of the scope waveforms, yellow trace is CVDD and blue is CVDD1.

Thanks,

Jack
