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 UHCI controller #1 or the 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 UHCI controller #2 or the EHCI controller.
NOTE: No external resistors are required on these signals. The ICH5
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 UHCI controller #3 or the EHCI controller.
NOTE: No external resistors are required on these signals. The ICH5
Universal Serial Bus Port 7:6 Differential: These differential pairs are used to
transmit Data/Address/Command signals for ports 6and 7. These ports can be
routed to UHCI controller #4 or the EHCI controller.
NOTE: No external resistors are required on these signals. The ICH5
Overcurrent Indicators: These signals set corresponding bits in the USB
controllers to indicate that an overcurrent condition has occurred.
OC[7:4]# may optionally be used as GPIs.
USB Resistor Bias: These are analog connection point for an external resistor
to ground.
