QIt has been pointed out that the datasheet (version E) has changed its
recommendation with respect to the grounding of the bottom pad (EPAD). As per
the recommendation (ver D), we left the EPAD floating and manufactured the
PCB's. It was now noted that on the Eval board and ver E, it is connected to
AThe LFCSP exposed paddle is used only for mechanical stability and for this
reason should be connected to a large pad on your PCB. The exposed paddle is
not connected to any internal signal on any of the ADUC702x parts therefore,
there is no need to connect a track to the paddle on your PCB - not even AGND.
