Universal Serial Bus Port 1:0 Differential: These differential pairs are used to
transmit data/address/command signals for ports 0 and 1. These ports can be
routed to USB UHCI controller #1 or the USB EHCI controller.
NOTE: No external resistors are required on these signals. The Intel
Universal Serial Bus Port 3:2 Differential: These differential pairs are used to
transmit data/address/command signals for ports 2 and 3. These ports can be
routed to USB UHCI controller #2 or the USB EHCI controller.
NOTE: No external resistors are required on these signals. The ICH4
Universal Serial Bus Port 5:4 Differential: These differential pairs are used to
transmit data/address/command signals for ports 4 and 5. These ports can be
routed to USB UHCI controller #3 or the USB EHCI controller.
NOTE: No external resistors are required on these signals. The ICH4
Overcurrent Indicators: These signals set corresponding bits in the USB
controllers to indicate that an overcurrent condition has occurred.
USB Resistor Bias: Analog connection point for an external resistor to ground.
USBRBIAS should be connected to USBRBIAS# as close to the resistor as
possible.
USB Resistor Bias Complement: Analog connection point for an external
resistor to ground. USBRBIAS# should be connected to USBRBIAS as close to
the resistor as possible.
