Configuration Write
I. Type 0 Configuration Write: Ignore
II. Type 1 Configuration Write (not special cycle
request):Ignore
III. Configuration Write as Special Cycle Request (device
= 1Fh, function = 7h):
1. If the target bus is the bridge’s primary bus: claim and
pass through as a Special Cycle
2. If the target bus is neither the primary bus nor is it in range
of buses defined by the bridge’s secondary and subordinate
bus registers: claim and pass through unchanged as a Type 1
Configuration Write.
3. If the target bus is not the bridge’s primary bus, but is in
range of buses defined by the bridge’s secondary and
subordinate bus registers: ignore.
