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 = Master abort not generated by bus master AC ‘97 function.
1 = Bus Master AC ‘97 interface function, as a master, generates a master abort.
Reserved. 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 Intel
timing parameter. These read only bits indicate the ICH5's DEVSEL# timing when performing a
positive decode.
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 ICH5 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 (CAP_LIST) — RO. Indicates that the controller contains a capabilities pointer list.
The first item is pointed to by looking at configuration offset 34h.
Interrupt Status (INTS) — RO.
0 = This bit is 0 after the interrupt is cleared.
1 = This bit is 1 when the INTx# is asserted.
Reserved
Revision ID — RO. Refer to the latest Intel
Revision Identification register.
