TAS2563YBGEVM-DC: How to use the eval board without motherboard PPC3-EVM-MB

Part Number: TAS2563YBGEVM-DC
Other Parts Discussed in Thread: PPC3-EVM-MB

I am trying to use the eval kit without the PPC3-EVM-MB. I have provided VBAT of 5V, but I'm getting a NACK. Upon further probing, I noticed that IOVDD1 and VDD are at 0V. Please suggest appropriate settings here. Do these need to be provided externally? 3.3V seems doable, but 1.8V might be tricky. Please advise.

RESOLVED, connected IOVDD to 3V, provided 1.8V and 3.3V inputs on J2
