Note
11. Pins are Do Not Use (DNU) on devices without USB. The pin must be left floating.
The two pins labeled Vddd must be connected together.
The two pins labeled Vccd must be connected together, with capacitance added, as shown in
page 29. The trace between the two Vccd pins should be as short as possible.
The two pins labeled Vssd must be connected together.
