Do not claim. Ignore.
1. If address is within pass through I/O range, claim and pass through.
2. Otherwise, do not pass through and do not claim for internal access.
Same as I/O Read.

1. If address is within pass through memory range, claim and pass
through.
2. If address is within pass through memory mapped I/O range, claim and
pass through.
3. Otherwise, do not pass through and do not claim for internal access.
Same as Memory Read.

Type 0 Configuration Read:
If the bridge’s IDSEL line is asserted, perform function decode and claim
if target function is implemented. Otherwise, ignore. If claimed, permit
access to target function’s configuration registers. Do not pass through
under any circumstances.
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.
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
Same as Memory Read
