Ground. Must be tied to ground.
Device Reset. Open-drain output of internal POR or V
nal source can initiate a system reset by driving this pin low for the time
specified in Table 4.
VBUS Sense Input. This pin should be connected to the VBUS signal of a
USB network.
Connect a 4.7 µF capacitor between this pin and ground to support ROM
programming via the USB interface.
