Determines transceiver D+, D- output characteristics.
0 = Low speed. 1 = Full speed. Transceivers with I
interfaces can implement this functionality as a control bit
rather than a pin.
Controls transceiver powerdown modes.
0 = Active mode.
1 = Low-power mode
2
Transceivers with I C interfaces can implement this
functionality as a control bit rather than a pin.
