Example 2 Trace Result
When the trigger occurs, trace port outputs a special trigger message called Watchpoint, frame 0
above. This is detected by the external trace hardware and recorded as a trigger event. Recorded
trigger message is depicted with a red frame in the trace window.
In this example, we can see that actual Type_Simple() function started 3 frames after the Watchpoint
message. This is due to a delay between the time when the instruction was executed and the time
when belonging message is broadcast externally. It is user’s concern to search for the code that
actually generated the trigger message. The distance from the trigger frame to the actual trigger point
in the reconstructed program also depends on the number of sequential instructions following the
trigger event.
