1. Specified by design - Not tested in production.
2. Measured from 10% to 90% of the data signal. For more detailed information, refer to USB specification -
chapter 7 (version 2.0).
3. No external termination series resistors are required on DP (D+) and DM (D-) pins since the matching
impedance is included in the embedded driver.
