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
