0b — Do not drive V
1b — Drive 5 V on V
Charge V
first check that V
data lines have been LOW (SE0) for 2 ms.
0b — Do not charge V
1b — Charge V
Discharge V
for an RXCMD indicating that SESS_END has changed from 0 to 1, and then resets this bit to

0b — Do not discharge V
1b — Discharge V
DM Pull Down: Enables the 15 k pull-down resistor on DM.
0b — Pull-down resistor is not connected to DM.
1b — Pull-down resistor is connected to DM (default).
DP Pull Down: Enables the 15 k pull-down resistor on DP.
0b — Pull-down resistor is not connected to DP.
1b — Pull-down resistor is connected to DP (default).
ID Pull Up: Connects a pull-up to the ID line and enables sampling of the ID level. Disabling
the ID line sampler will reduce PHY power consumption.
0b — Disables sampling of the ID line (default).
1b — Enables sampling of the ID line.
