TAS2110EVM: TAS2110 - PPC3 config implemented, bad VBAT data

Part Number: TAS2110EVM

Tool/software:

Hi ! 

I used PPC3 to generate config, I pushed the config via i2c. 
When I try to read back vbat, I get 0's. 

Is there an extra step to power this on?
I tried writing 0x00 to register 0x02 on page 0. 

Are there any other sanity checks to determine if this device is up and running? Thanks.
