DESCRIPTION
Reset to 0b.
DESCRIPTION
Reset to 000b.
Indicates that an INTx Interrupt Message is pending internally to the device.
In the Switch, the forwarding of INTx messages from the downstream device
of the Switch port is not reflected in this bit. Must be hardwired to 0b.
Set to 1 to enable support for the capability list (offset 34h is the pointer to
the data structure).
Reset to 1b.
Does not apply to PCI Express. Must be hardwired to 0b.
Reset to 0b.
Does not apply to PCI Express. Must be hardwired to 0b.
Set to 1 (by a requester) whenever a Parity error is detected or forwarded on
the primary side of the port in a Switch.
If the Parity Error Response Enable bit is cleared, this bit is never set.
Reset to 0b.
Does not apply to PCI Express. Must be hardwired to 0b.
Set to 1 (by a completer) whenever completing a request on the primary side
using the Completer Abort Completion Status.
Reset to 0b.
Set to 1 (by a requestor) whenever receiving a Completion with Completer
Abort Completion Status on the primary side.
Reset to 0b.
Set to 1 (by a requestor) whenever receiving a Completion with Unsupported
Request Completion Status on primary side.
Reset to 0b.
Set to 1 when the Switch sends an ERR_FATAL or ERR_NONFATAL
Message, and the SERR Enable bit in the Command register is 1.
Reset to 0b.
Set to 1 whenever the primary side of the port in a Switch receives a Poisoned
TLP.
Reset to 0b.
DESCRIPTION
Indicates revision number of device. Hardwired to 02h.
DESCRIPTION
Read as 00h to indicate no programming interfaces have been defined for
PCI-to-PCI Bridges.
Read as 04h to indicate device is a PCI-to-PCI Bridge.
Read as 06h to indicate device is a Bridge device.
