Description
EHCI Pin (EIP) — R/W. This field indicates which pin the EHCI controller drives as
its interrupt.
0h = No interrupt
1h = INTA# (Default)
2h = INTB#
3h = INTC#
4h = INTD#
5h–Fh = Reserved
Reserved
UHCI #3 Pin (U3P) — R/W. This field indicates which pin the UHCI controller #3
(ports 6 and 7) drives as its interrupt.
0h = No interrupt
1h = INTA#
2h = INTB#
3h = INTC#
4h = INTD# (Default)
5h–Fh = Reserved
UHCI #2 Pin (U2P) — R/W. This field indicates which pin the UHCI controller #2
(ports 4 and 5) drives as its interrupt.
0h = No interrupt
1h = INTA#
2h = INTB#
3h = INTC# (Default)
4h = INTD#
5h–Fh = Reserved
UHCI #1 Pin (U1P) — R/W. This field indicates which pin the UHCI controller #1
(ports 2 and 3) drives as its interrupt.
0h = No interrupt
1h = INTA#
2h = INTB# (Default)
3h = INTC#
4h = INTD#
5h–Fh = Reserved
UHCI #0 Pin (U0P) — R/W. This field indicates which pin the UHCI controller #0
(ports 0 and 1) drives as its interrupt.
0h = No interrupt
1h = INTA# (Default)
2h = INTB#
3h = INTC#
4h = INTD#
