Data Trace, Data Read with Sync (DTDRS)
This message is an alternative to the Data Trace, Data Read Message. It is output instead of a
Data Trace, Data Read Message whenever a memory read occurs that matches the debug
logic’s data trace attributes, and when one of the following conditions has occurred:
The processor has exited from reset. This synchronization message is required to allow the
unique portion of the data write address of following Data Trace, Data Read Messages to be cor-
rectly interpreted by the tool.
When enabling data trace is during normal execution of the embedded processor.
Upon exit from a power-down state. This synchronization message is required to allow the
unique portion of the data write address of following Data Trace, Data Read Messages to be cor-
rectly interpreted by the tool.
The Event-In pin has been asserted and a debug control register field specifies that EVTI pin
action is to generate data trace synchronization.
An overrun condition had previously occurred in which one or more data trace occurrences were
discarded by the target processor’s debug logic. To inform the tool that an overrun condition
occurred, the target outputs an Error Message (TCODE = 8) with an ECODE value of 00010 or
00111 immediately prior to the Data Trace, Data Read with Sync Message.
The periodic Data Trace Message counter has expired indicating that 255 without-sync versions
of Data Trace Messages have been sent since the last with-sync version.
A data read is detected following the processor exiting from Debug Mode.

The full address of the memory location written. Most significant
bits that have a value of 0 are truncated.
