4.5 Messaging Unit Error Conditions
The Messaging Unit, like the ATU, encounters error conditions on the host I/O interface
as well as the internal bus interface. As a host I/O interface target, all host I/O
interface errors are captured and recorded in the ATU Status Register and can be
masked using the ATU mechanisms. Refer to Chapter 2.0, “Address Translation Unit
(PCI-X)” or Chapter 3.0, “Address Translation Unit (PCI Express)” for further details.
