D I/O
Device Reset. Open-drain output of internal POR or VDD monitor. An
external source can initiate a system reset by driving this pin low for at
least 15 s.
REGIN

D In
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.
