rences 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 Write with
Sync Message.
versions of Data Trace Messages have been sent since the last with-sync version.

Direction: From target
Description
The data value written. The size will vary depending on the load /
store instruction being traced.
The full address of the memory location written. Most significant
bits that have a value of 0 are truncated.
Data size:
00 = 8 bits
01 = 16 bits
10 = 32 bits
Value=13
Direction: From target
Description
The data value read. The size will vary depending on the load /
store instruction being traced.
The unique portion of the data read address, which is relative to
the previous Data Trace Message (read or write).
Data size:
00 = 8 bits
01 = 16 bits
10 = 32 bits
Value=6
