Function
32-bit Indicator
I/O Base Address
[15:12]
Type
R/O
R/W
Description
Read as 01h to indicate 32-bit I/O addressing
Defines the bottom address of the I/O address range for the bridge
to determine when to forward I/O transactions from one interface to
the other. The upper 4 bits correspond to address bits [15:12] and
are writable. The lower 12 bits corresponding to address bits [11:0]
are assumed to be 0. The upper 16 bits corresponding to address
bits [31:16] are defined in the I/O base address upper 16 bits address
register
Reset to 0

Type
R/O
R/O
Description
Reset to 0
Set to 1 to enable 66MHz operation on the secondary (S1 or S2)
interface
Reset to 1
Reset to 0
Set to 1 to enable decoding of fast back-to-back transactions on the
secondary (S1 or S2) interface to different targets
Reset to 0
Set to 1 when S1_PERR# or S2_PERR# is asserted and bit 6 of
command register is set
Reset to 0
DEVSEL# timing (medium decoding)
00: fast DEVSEL# decoding
01: medium DEVSEL# decoding
10: slow DEVSEL# decoding
11: reserved
Reset to 01
Set to 1 (by a target device) whenever a target abort cycle occurs on
its secondary (S1 or S2) interface
Reset to 0
