Data Trace
Registers
Overview
Program Trace Correlation
Program Trace Correlation messages are used to correlate events to the program flow that may
not be associated with the instruction stream (e.g. Data Trace Messages). The occurrence of an
event listed in Table 9-41 will cause this message to be transmitted.
Table 9-41.
Table 9-42.
Program trace is enabled using the TM field in the Development Control register.
The AVR32 OCD system provides data trace via the AUX port. The CPU data memory accesses
can be monitored real-time using the Nexus class 2+ compliant Data Trace Unit. Both reads and
writes can be traced.
Data Trace information is transmitted through data trace messages, which can be of read or
write type, with or without sync. The messages contain information about the data address and
value which triggered the trace. Data addresses can be complete (with sync), or compressed
relative to the previous transmitted message (without sync). The value contains the data value
read or written from the data cache, and is of the same width as the access size (byte, halfword,
word, or doubleword).
The TM[1] bit in the Development Control register must be set to enable data trace. It is also
possible to trigger data trace using watchpoints. In this case, TM[1] will be set or cleared
automatically.
