This register could be used by the SMI# handler to assist in determining what was the
last cycle from the processor. BUS_ADDR_TRACK may not contain “expected” last I/O
cycle data when Asynchronous SMIs and Synchronous SMIs are occurring
simultaneously. This register only reports “expected” last I/O cycle data when
Asynchronous SMIs are disabled.

Corresponds to the low 16 bits of the last I/O cycle, as would
be defined by the PCI AD[15:0] signals on the PCI bus (even
though it may not be a real PCI cycle). The value is latched
based on SMI# active. This functionality is useful for figuring
out which I/O was last being accessed.
