Note 1: All voltages are measured from the local ground potential, unless otherwise specified.

Note 2: All timing use a capacitive load (CL) to ground of 50pF, unless otherwise specified.

Note 3: This is relative to VUSBIN.

Note 4: This is dependent on block configuration set by software.

Note 5: When the internal ring oscillator and waiting for first setup packet.
