WICED Studio Bluetooth

I was looking for any requirements or recommendations about the proper power-up sequencing for the CYW20179 (QFN Package).

In the Device Data Sheet I see a requirement that VDDO should be up and stable for a minimum of 35ms before releasing Reset, but is there any recommendation or requirement with regard to sequencing of SR_VDDBAT3V and VDDO?

The VDDO and VDDBAT are usually powered by the same source. There isn't strict requirement for them.
