Description
Enhanced capabilities port offset pointer. Read as B0h to indicate
that the first item resides at that configuration offset.
Description
Controls the bridge’s response to parity errors on the secondary
interface.
0: ignore address and data parity errors on the secondary interface
1: enable parity error reporting and detection on the secondary
interface
Reset to 0
Controls the forwarding of S1_SERR# or S2_SERR# to the primary
interface.
0: disable the forwarding of S1_SERR# or S2_SERR# to primary
interface
1: enable the forwarding of S1_SERR# or S2_SERR# to primary
interface
