PCISTS—PCI Status Register
(LAN Controller—B1:D8:F0)
Offset Address: 06h
Default Value:
For the writable bits, software must write a 1 to clear bits that are set. Writing a 0 to
the bit has no effect.

Detected Parity Error (DPE) — R/WC.
0 = Parity error Not detected.
1 = The Intel
Signaled System Error (SSE) — R/WC.
0 = Integrated LAN controller has not asserted SERR#
1 = The ICH7’s integrated LAN controller has asserted SERR#. SERR# can be routed to
Master Abort Status (RMA) — R/WC.
0 = Master Abort not generated
1 = The ICH7’s integrated LAN controller (as a PCI master) has generated a master
Received Target Abort (RTA) — R/WC.
0 = Target abort not received.
1 = The ICH7’s integrated LAN controller (as a PCI master) has received a target abort.
Signaled Target Abort (STA) — RO. Hardwired to 0. The device will not signal Target
Abort.
DEVSEL# Timing Status (DEV_STS) — RO.
01h = Medium timing.
Data Parity Error Detected (DPED) — R/WC.
0 = Parity error not detected (conditions below are not met).
1 = All of the following three conditions have been met:
1.
2.
3.
Fast Back to Back Capable (FB2BC) — RO. Hardwired to 1. The device can accept fast
back-to-back transactions.
User Definable Features (UDF) — RO. Hardwired to 0. Not implemented.
66 MHz Capable (66MHZ_CAP) — RO. Hardwired to 0. The device does not support 66
MHz PCI.
Capabilities List (CAP_LIST) — RO.
0 = The EEPROM indicates that the integrated LAN controller does not support PCI
1 = The EEPROM indicates that the integrated LAN controller supports PCI Power
Interrupt Status (INTS) — RO. This bit indicates that an interrupt is pending. It is
independent from the state of the Interrupt Enable bit in the command register.
