Master Data Parity Error Detected. This bit is set by the bridge
function if the PERRE bit in the PCI Command register (PCICMD)
is set to 0x1 and either of the following two conditions occurs: the
function receives a Poisoned Completion going Downstream, or
the function transmits a Poisoned Request Upstream.
DEVSEL# TIming. Not applicable.
Signaled Target Abort. This bit is set when the bridge completes
a posted or non-posted request with a completer-abort error. In the
switch, this bit is set when the bridge blocks a multicast TLP
received on its primary side.
Received Target Abort. Not applicable (the bridge function never
generates requests on its own behalf).
Received Master Abort. Not applicable (the bridge function never
generates requests on its own behalf).
Signaled System Error. This bit is set when the bridge function
sends a ERR_FATAL or ERR_NONFATAL message and the
SERR Enable (SERRE) bit is set in the PCICMD register.
0x0 - (noerror) no error.
0x1 - (error) This bit is set when a fatal or non-fatal error is sig-
naled.
Detected Parity Error. This bit is set by the bridge function when-
ever it receives a poisoned TLP on the primary side regardless of
the state of the PERRE bit in the PCI Command (PCICMD) regis-
ter.
