Relative Addressing
Refer to
Section 24.9.2.6, “Relative Addressing
,” for further details.
24.9.3
Queue Overflow Data Trace Error Message
A program/data/ownership trace overrun error or data trace error occurs when a trace message cannot be
queued due to the queue being full, provided data trace is enabled.
The overrun error causes the message queue to be flushed, and an error message to be queued. The error
code within the error message indicates that a program/data/ownership trace overrun error has occurred.
The next DTM will be a synchronization message. Refer to
.
The error message has the following format:

24.9.4
Data Trace Operation
Data trace is performed by snooping the L-bus for read or write cycles. Data trace functions are enabled
by setting the appropriate fields in the DC register and the DTA registers. For details on field configuration,
