AD7616 power supply sequencing

Hi

I have two questions about AD7616.

Would you tell me the answer about these?

Question 1

Is there any problem if sequence is to power up VCC slightly first , followed by VDRIVE?



Question 2

Regarding to absolute maximum ratings of VDRIVE to AGND.

This rating is -0.3V to VCC + 0.3V, but recommended sequence is to power up VDRIVE first , followed by VCC.

Would you please explain these contents?

Best Regards,
