Note 4.4 The resistor value follows the 27% Resistor ECN published by the USB-IF.
Note 4.5 The values shown are valid when the USB RegOutput bits in the USB IO & Power
Management register are set to the default value.
Note 4.6 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.
