[1] HS termination resistor is disabled, and pull-up resistor is connected. Occurs only during reset when both hub and device are
high-speed capable.
[2] Includes internal matching resistors on both D+ and D−. This tolerance range complies with USB specification 2.0.
[3] In the ‘suspend’ mode, the minimum voltage is 2.7 V.
