Detected Parity Error (DPE) — RO. Not implemented. Hardwired to 0.
Signaled System Error (SSE) — RO. Not implemented. Hardwired to 0.
Master Abort Status (MAS) — R/WC.
0 = Software clears this bit by writing a 1 to the bit position.
1 = Bus Master AC '97 2.3 interface function, as a master, generates a master abort.
Reserved. Will always read as 0.
Signaled Target Abort (STA) — RO. Not implemented. Hardwired to 0.
DEVSEL# Timing Status (DEV_STS) — RO. This 2-bit field reflects the ICH4's DEVSEL# timing
when performing a positive decode.
01b = Medium timing.
Data Parity Error Detected (DPED) — RO. Not implemented. Hardwired to 0.
Fast Back to Back Capable (FB2BC) — RO. Hardwired to 1. This bit indicates that the ICH4 as a
target is capable of fast back-to-back transactions.
User Definable Features (UDF) — RO. Not implemented. Hardwired to 0.
66 MHz Capable (66MHZ_CAP) — RO. Hardwired to 0.
Capabilities List (CLIST) — RO. Indicates that the controller contains a capabilities pointer list. The
first item is pointed to by looking at configuration offset 34h.
