17.4.1.2
Whenever data must cross a bridge between two busses, the byte ordering of data on the source and
destination buses must be considered. The internal platform bus of this device is inherently big endian and
the PCI Express bus interface is inherently little endian.
There are two methods to handle ordering of data as it crosses a bridge—address invariance and data
invariance. Address invariance preserves the addressing of bytes within a scalar data element, but not the
relative significance of the bytes within that scalar. Conversely, data invariance preserves the relative
significance of bytes within a scalar, but not the addressing of the individual bytes that make up a scalar.
This device uses address invariance as its byte ordering policy.
As stated above, address invariance preserves the byte address of each byte on an I/O interface as it is
placed in memory or moved into a register. This policy can have the effect of reversing the significance
order of bytes (most significant to least significant and vice versa), but it has the benefit of preserving the

Memory Read Request
Memory Read Lock. As a target, CplLk with UR status is returned.
Memory Write Request to memory-mapped PCI-Express space
I/O Read request. As a target, Cpl with UR status is returned.
I/O Write Request. As a target, Cpl with UR status is returned.
Configuration Read Type 0
Configuration Write Type 0
Configuration Read Type 1. As a target, Cpl with UR status is returned.
Configuration Write Type 1. As a target, Cpl with UR status is returned.
Message Request
only message with data that is supported and then only when the controller is
an initiator and in RC mode or a target and in EP mode.
Completion without Data
Completion with Data
Completion for Locked Memory Read without Data. The only time that CplLk is
returned with UR status is when the controller receives a MRdLk command.
