XIO2001 - "support legacy subractive I/O space decode"?

Other Parts Discussed in Thread: XIO2001

Hello:

I am looking for a PCIe to PCI bridge IC that supports “legacy subtractive I/O space decode”, so that I can use a PCI to ISA bridge IC downstream, and get ISA I/O addresses through the bridge chips.  Does the TI XIO2001 support this feature?

Any feedback or input is welcomed and appreciated!

Thanks again!

Paul
