Description
regulated supply voltage (3.3 V ± 10%) from internal
regulator; used to connect pull-up resistor on DP0 line
modes 4 to 6: power switch control output for downstream
port 2 (open-drain, 6 mA)
modes 0 to 3, 7: GoodLink LED indicator output for
downstream port 2 (open-drain, 6 mA); to connect an LED
use a 330 Ω series resistor
