A.
The shaded terminals are used for electrical and thermal connections to the ground plane. All of the shaded terminals
must be electrically connected to ground. No connect (NC) terminals still need a pad and trace.
B.
The thermal pad of the DRB and DGN packages must be electrically and thermally connected to a ground plane.
