If internal regulator is enabled, connect all of the AVdd_Core and/or DVdd_Core pins together to a common floating plane and bypass to Vss.
If internal regulator is NOT enabled, it is recommended that all AVdd_Core pins be tied to a plane at 1.2V, that is bypassed to ground. DVdd_Core
can be tied to this plane or separately decoupled.
IC ground (Vss) is established by contact with exposed pad on underside of package; there are no Vss pins.
