data on its secondary interface. The counter starts counting down from the assertion of
PXFRAME#. When the grant is removed, the expiration of this counter results in the
deassertion of PXFRAME#. When the grant has not been removed, the Intel
ICH may continue ownership of the bus. The secondary latency timer's default value
should be 64 in PCI-X mode (Section 8.6.1 of the PCI-X 1.0 Specification).

Indicates the highest PCI bus number below this bridge. Any
type one configuration cycle on the Hub Interface whose bus
number is greater than the secondary bus number and less
than or equal to the subordinate bus number is run as a type
one configuration cycle on the PCI bus.
Indicates the bus number of PCI to which the secondary
interface is connected. Any type one configuration cycle
matching this bus number is translated to a type 0
configuration cycle and run on the PCI bus.
Indicates the bus number of the Hub Interface. Any type 1
configuration cycle with a bus number less than this number
is not accepted by this portion of the Intel
(i.e., it still may match the other bridge).
A five-bit value that indicates the number of PCI clocks, in 8-
clock increments, that the Intel
master of the PCI bus when another master is requesting use
of the PCI bus.
