Active Low output interrupt signal. Active when a SE0 is detected while in HNP
mode. This pin has an internal 220 kΩ pull-down to ground when HIGHZ=”H” only.
Data line pull-up supply voltage. Connect an external 1.5 kΩ resistor to D+ (full-

pin and the connection of internal weak pull-up resistor. LOW: VPU floating
(SUSPEND=”0” or “1”). HIGH: VPU = 3.3 V. Functionality can change depending on
status of SPEED# and SUSPEND pins. See Table 12 for more details.
