Description
31:0
I/O Limit
Address, Upper
16-bits [31:16]
R/W
Defines the upper 16-bits of a 32-bit top address of an address range
for the bridge to determine when to forward I/O transactions from
one interface to the other.

BRIDGE CONTROL REGISTER – OFFSET 3Ch
Bit
Function
Type
Description
16
Parity Error
Response
R/W
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
17
S1_SERR#
enable
R/W
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
Reset to 0
18
ISA enable
R/W
Modifies the bridge’s response to ISA I/O addresses, applying only to
those addresses falling within the I/O base and limit address registers
and within the first 64KB or PCI I/O space.
0: forward all I/O addresses in the range defined by the I/O base and
I/O limit registers
1: blocks forwarding of ISA I/O addresses in the range defined by the
I/O base and I/O limit registers that are in the first 64KB of I/O space
that address the last 768 bytes in each 1KB block. Secondary I/O
transactions are forwarded upstream if the address falls within the last
768 bytes in each 1KB block
