ICH8 Family Datasheet
PSTS—PCI Status Register (PCI-PCI—D30: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.

Memory Write and Invalidate Enable (MWE) — RO. Hardwired to 0, per the PCI
Express* Base Specification, Revision 1.0a
Special Cycle Enable (SCE) — RO. Hardwired to 0, per the PCI Express* Base
Specification, Revision 1.0a and the PCI- to-PCI Bridge Specification.
Bus Master Enable (BME) — R/W.
0 = Disable
1 = Enable. Allows the PCI-to-PCI bridge to accept cycles from PCI.
Memory Space Enable (MSE) — R/W. Controls the response as a target for memory
cycles targeting PCI.
0 = Disable
1 = Enable
I/O Space Enable (IOSE) — R/W. Controls the response as a target for I/O cycles
targeting PCI.
0 = Disable
1 = Enable
Detected Parity Error (DPE) — R/WC.
0 = Parity error Not detected.
1 = Indicates that the ICH8 detected a parity error on the internal backbone. This bit
gets set even if the Parity Error Response bit (D30:F0:04 bit 6) is not set.
