Description
EHCI #2 Pin (E2IP) — R/W. Indicates which pin the EHCI controller #2 drives as its
interrupt:
0h = No Interrupt
1h = INTA#
2h = INTB#
3h = INTC# (Default)
4h = INTD#
5h-Fh = Reserved
31:28
27:12
Reserved
UHCI #6 Pin (U2P) — R/W. Indicates which pin UHCI controller #6 (Device 26
Function 2) drives as its interrupt, if controller exists.
0h = No Interrupt
1h = INTA#
2h = INTB#
3h = INTC# (Default)
11:8
4h = INTD#
5h-Fh = Reserved
NOTE: This field should be set to 0h when UHCI Controller #6 Remap bit (RCBA
offset 35F0h:bit 0) is set to 1.
UHCI #5 Pin (U1P) — R/W. Indicates which pin UHCI controller #5 (Device 26
Function 1), drives as its interrupt.
0h = No Interrupt
1h = INTA#
2h = INTB# (Default)
3h = INTC#
4h = INTD#
5h-Fh = Reserved
7:4
3:0
UHCI #4 Pin (U0P) — R/W. Indicates which pin UHCI controller #4 (Device 26
Function 0), drives as its interrupt.
0h = No Interrupt
1h = INTA# (Default)
2h = INTB#
3h = INTC#
4h = INTD#
5h-Fh = Reserved
