Note 4-5 The resistor value follows the 27% Resistor ECN published by the USB-IF.
Note 4-6 The values shown are valid when the USB RegOutput bits in the USB IO & Power Management
register are set to the default value.
Note 4-7 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.
