Ground. Must be tied to ground.
Device Reset. Open-drain output of internal POR or V
external source can initiate a system reset by driving this pin low for
at least 15 µs.
5 V Regulator Input. This pin is the input to the on-chip voltage regu-
lator.
VBUS Sense Input. This pin should be connected to the VBUS signal
of a USB network. A 5 V signal on this pin indicates a USB network
connection.
