Notes:
1. The symbols used for timing specifications follow the pattern of t
2. All timings are in reference to USB clock.
3. All signals are measured from NVDD/2 of the rising edge of USB clock to 0.4 × NVDD of the signal in question for 3.3-V
4. Input timings are measured at the pin.
5. For purposes of active/float timing measurements, the Hi-Z or off-state is defined to be when the total current delivered
