adv7431 power up sequence

Regarding adv7431 power up sequence

There is a power up sequence requirement between VDDIO and VDD.

VDDIO should rise before VDD, but when they share the same power (1.8V) should they be sequenced as well or can they power @ the same time?

 

BTW- there is no requirement for VAA and PVDD (PLL VDD)  - they can be powered any time ?

 

Thanks
