0b — Do not discharge V
1b — Discharge V
DM Pull Down: Enables the 15 kΩ 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 kΩ 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.
