ADuM3160 speed config

I have an application using the ADuM3160 where the customer wants to be able to dynamically select between lo-speed and full-speed mode.  The datasheet says that the part cannot make this adjustment on the fly so I added provision to cycle power on both sides of the isolator.

 

Are there any power sequencing requirements for Vbus1 and Vbus2?

 

What are the timing requirements for the SPD/SPU pins being set with respect to their power rails coming up?

 

Thanks,

Matt
