Note 4-6
The resistor value follows the 27% Resistor ECN published by the USB-IF.
Note 4-7
The values shown are valid when the USB RegOutput bits in the USB IO & Power Management
register are set to the default value.
Note 4-8
An automatic waiver up to 200mV is granted to accommodate system-level elements such as
measurement/test fixtures, captive cables, EMI components, and ESD suppression. This parameter
can be tuned using VariSense technology, as defined in the HS Compensation Register section of
Section 7.0, "ULPI Register Map".
