Command
Action
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

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.

CONFIGURATION REGISTERS
As PI7C7300D supports two secondary interfaces, it has two sets of configuration
registers that are almost identical and accessed through different function numbers. PCI
configuration defines a 64-byte space (configuration header) to define various attributes
of the PCI-to-PCI Bridge as shown below. There are two configuration registers:
