Detected Parity Error (DPE) — R/WC.
0 = Parity error not detected.
1 = Intel
Received System Error (RSE) — R/WC.
0 = SERR# assertion not received
1 = SERR# assertion is received on PCI.
Received Master Abort (RMA) — R/WC.
0 = No master abort.
1 = This bit is set whenever the bridge is acting as an initiator on the PCI bus and the
Received Target Abort (RTA) — R/WC.
0 = No target abort.
1 = This bit is set whenever the bridge is acting as an initiator on PCI and a cycle is
Signaled Target Abort (STA) — R/WC.
0 = No target abort.
1 = This bit is set when the bridge is acting as a target on the PCI Bus and signals a
DEVSEL# Timing (DEVT) — RO.
01h = Medium decode timing.
Data Parity Error Detected (DPD) — R/WC.
0 = Conditions described below not met.
1 = The ICH7 sets this bit when all of the following three conditions are met:
Fast Back to Back Capable (FBC) — RO. Hardwired to 1 to indicate that the PCI to PCI
target logic is capable of receiving fast back-to-back cycles.
Reserved
66 MHz Capable (66MHZ_CAP) — RO. Hardwired to 0. This bridge is 33 MHz capable
only.
Reserved
• The bridge is the initiator on PCI.
• PERR# is detected asserted or a parity error is detected internally
• BCTRL.PERE (D30:F0:3E bit 0) is set.
