Detected Parity Error (DPE) — R/WC.
0 = This bit is cleared by writing a 1 to the bit location.
1 = The Intel
Signaled System Error (SSE)
0 = This bit is cleared by writing a 1 to the bit location.
1 = The ICH4’s integrated LAN controller has asserted SERR#. (SERR# can be routed to cause
Master Abort Status (MAS) — R/WC.
0 = This bit is cleared by writing a 1 to the bit location.
1 = The ICH4’s integrated LAN controller (as a PCI master) has generated a master abort.
Received Target Abort (RTA) — R/WC.
0 = This bit is cleared by writing a 1 to the bit location.
1 = The ICH4’s integrated LAN controller (as a PCI master) has received a target abort.
Signaled Target Abort (STA) — RO. Hardwired to 0. The device will never signal Target Abort.
DEVSEL# Timing Status (DEV_STS) —RO.
01h = Medium timing.
Data Parity Error Detected (DPED) — R/WC.
0 = This bit is cleared by writing a 1 to the bit location.
1 = All of the following three conditions have been met:
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 Power
1 = The EEPROM indicates that the integrated LAN controller supports PCI Power Management.
Reserved
1. The LAN controller is acting as bus master
2. The LAN controller has asserted PERR# (for reads) or detected PERR# asserted (for writes)
3. The Parity Error Response bit in the LAN controller’s PCI Command Register is set.
