I/O BASE REGISTER – OFFSET 1Ch
Bit
3:0
7:4
Function
32-bit Indicator
I/O Base Address
[15:12]
Type
R/O
R/W
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
