Action
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
