Table 18.17 Sie Completion Status - Hitachi HD64465 User Manual

When a transaction completes, the completion status is reported to the List Processor. The SIE
can compile all error information to create the CompletionCode field for the TD writeback,
but may be overridden by the List Processor. Table 18-17 shows the transaction status (nearly
identical to the CompletionCode) definitions generated by the SIE to the List Processor. Table
18-18 and Table 18-19 show the prioritization of transaction status used by the SIE to create the
encoding.
