Trace Window
Choosing the Trace command from the View –> Debug Windows menu
opens the Trace window ( Figure 2-1 ).
The trace buffer stores a history of the last 16 changes in program flow
taken by the program sequencer. View the history to recreate the program
sequencer’s most recent path.
The trace buffer does not track changes in flow caused by zero-overhead
loops or while in the reset service routine.
L
To use the trace buffer, ensure your program leaves the reset service
routine.
Enabling Trace Buffer
To view trace history in the Trace window, first, enable the trace buffer
(choose Enable Trace from the Tools –> Trace menu). On each halt, the
Trace window is updated with the changes that occurred since the last
halt. Reading the trace buffer destroys the trace buffer’s contents and dis-
cards the information previously stored before the last run.
