ADE9153A VAMS to Phase Connection

Hi,

I am using ADE9153A for a design of a smart plug. I'm having trouble understanding the connection from VAMS to Phase.

As mentioned in the datasheet VAMS should be connected to the phase. But as per the typical application circuit it is connected to the mSure voltage driver. Is the pin connected to the phase internally? If not should I connect it to the phase externally?

Best Regards,
