VGA enable
R/W
Controls the bridge’s response to VGA compatible addresses.
0: does not forward VGA compatible memory and I/O addresses from
primary to secondary
1: forward VGA compatible memory and I/O addresses from primary
to secondary regardless of other settings

Master Abort
Mode
R/W
Control’s bridge’s behavior responding to master aborts on secondary
interface.
0: does not report master aborts (returns FFFF_FFFFh on reads and
discards data on writes)
1: reports master aborts by signaling target abort if possible by the
assertion of P_SERR# if enabled
Reset to 0
22
Secondary
Interface Reset
R/W
Controls the assertion of S1_RESET# or S2_RESET# signal pin on
the secondary interface
0: does not force the assertion of S1_RESET# or S2_RESET# pin
1: forces the assertion of S1_RESET# or S2_RESET#
Reset to 0
23

Back Enable
R/W
Controls bridge’s ability to generate fast back-to-back transactions to
different devices on the secondary interface.
