BITS
7
Port Swap
This bit facilitates swapping the mapping of USBDP and USBDM.
0 = USBDP maps to the USB D+ line and USBDM maps to the USB D- line.
1 = USBDP maps to the USB D- line. USBDM maps to the USB D+ line.
6:5
PHY Boost
This field provides the ability to boost the electrical drive strength of the HS output current to the
upstream port.
00 = Normal electrical drive strength.
01 = Elevated electrical drive strength (+4% boost).
10 = Elevated electrical drive strength (+8% boost).
11 = Elevated electrical drive strength (+12% boost).
4
Duplex Detection
This bit determines whether duplex operational mode is detected automatically or manually set.
0 = Manual
1 = Automatic
3
Speed Detection
This bit determines whether operational speed is detected automatically or manually set.
0 = Manual
1 = Automatic
2
SPD_LED_FUNCTION
This bit specifies the functionality of speed LEDs
determined by line speed and the setting of this bit, as indicated in following table:

When SPD_LED_FUNCTION = 0, the LEDs function solely as Link and Speed LEDs. When
SPD_LED_FUNCTION = 1, the LEDs function as Link and Speed and Activity LEDs. In those cases,
the table entry “Blink” indicates the LED will remain on when no transmit or receive activity is detected
and will blink at an 80 mS rate whenever TX or RX activity is detected.
