TMS320F28377D: Power sequencing

Part Number: TMS320F28377D

Hello, in the datasheet for the 377D, section 5.7.1 is about power sequencing, but does not explicitly state that VDD needs to come up before VDDIO. Is there any reason that these two supplies cannot come up together or is it ok to have one supply up before the other?

Thank you for your time,

David
