Name Type Description
USBP0P,
USBP0N,
USBP1P,
USBP1N
I/O
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 EHCI Controller 1.
NOTE: No external resistors are required on these signals. The PCH
integrates 15 k pull-downs and provides an output driver
impedance of 45 which requires no external series resistor.
USBP2P,
USBP2N,
USBP3P,
USBP3N
I/O
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 EHCI Controller 1.
NOTE: No external resistors are required on these signals. The PCH
integrates 15 k pull-downs and provides an output driver
impedance of 45 which requires no external series resistor.
USBP4P,
USBP4N,
USBP5P,
USBP5N
I/O
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 EHCI Controller 1.
NOTE: No external resistors are required on these signals. The PCH
integrates 15 k pull-downs and provides an output driver
impedance of 45 which requires no external series resistor.
USBP6P,
USBP6N,
USBP7P,
USBP7N
I/O
Universal Serial Bus Port [7:6] Differential: These differential
pairs are used to transmit Data/Address/Command signals for ports 6
and 7. These ports can be routed to EHCI Controller 1.
NOTE: No external resistors are required on these signals. The PCH
integrates 15 k pull-downs and provides an output driver
impedance of 45 which requires no external series resistor.
USBP8P,
USBP8N,
USBP9P,
USBP9N
I/O
Universal Serial Bus Port [9:8] Differential: These differential
pairs are used to transmit Data/Address/Command signals for ports 8
and 9. These ports can be routed to EHCI Controller 2.
NOTE: No external resistors are required on these signals. The PCH
integrates 15 k pull-downs and provides an output driver
impedance of 45 which requires no external series resistor.

I/O
Universal Serial Bus Port [11:10] Differential: These differential
pairs are used to transmit Data/Address/Command signals for ports
10 and 11. These ports can be routed to EHCI Controller 2.
NOTE: No external resistors are required on these signals. The PCH
integrates 15 k pull-downs and provides an output driver
impedance of 45 which requires no external series resistor.
USBP12P,
USBP12N,
