August 22, 2002 – Revision 1.02
Type 1 Configuration Read:
1. If the target bus is the bridge’s secondary bus: claim and
pass through as a Type 0 Configuration Read.
2. If the target bus is a subordinate bus that exists behind the
bridge (but not equal to the secondary bus): claim and pass
through as a Type 1 Configuration Read.
3. Otherwise, ignore.
Type 0 Configuration Write: same as Configuration
Read.

Configuration Write
Type 1 Configuration Write (not special cycle request):
1. If the target bus is the bridge’s secondary bus: claim and
pass through as a Type 0 Configuration Write
2. If the target bus is a subordinate bus that exists behind the
bridge (but not equal to the secondary bus): claim and pass
through unchanged as a Type 1 Configuration Write.
3. Otherwise, ignore.
Configuration Write as Special Cycle Request
(device = 1Fh, function = 7h)
1. If the target bus is the bridges secondary bus:
claim and pass through as a special cycle.
2. If the target bus is a subordinate bus that exists
behind the bridge (but not equal to the secondary
bus): claim and pass through unchanged as a type
1 Configuration Write.
3. Otherwise ignore
