Select an available breakpoint or trigger condition to stop the stop-
watch. Available breakpoints/triggers are those previously added
to the breakpoint dialog.
Select None to clear the stop condition.
To halt the program run on this condition, check the check box next
to “Stop condition will cause the target device to halt”.
Reset stopwatch on run
Reset the stopwatch values to zero every time the program is run.
To set a breakpoint in code, do one of the following:
? Double click or right click on a line of code to set up an individual breakpoint.
? Select Debugger>Breakpoints to open the Breakpoints dialog and set up multiple
breakpoints and breakpoint conditions. See Section 9.3.1 “Breakpoints Dialog”
for more information.
To determine the time between the breakpoints, use the stopwatch:
1. Open the Breakpoints dialog ( Debugger>Breakpoints ).
1. Click Stopwatch on the Breakpoints dialog to open the Stopwatch dialog.
2. Under “Start Condition”, select a breakpoint from the drop-down list. Also decide
if “Start condition will cause the target device to halt”.
3. Under “Stop Condition”, select another breakpoint from the drop-down list. Also
decide if “Stop condition will cause the target device to halt”.
4. Decide if there will be a “Reset stopwatch on run”.
5. Click OK .

Event Breakpoints Dialog
Click Event Breakpoints in the Breakpoints Dialog to display this dialog.
Select a condition where the program will always break:
? Break on Watchdog Timer – Break every time the Watchdog Timer times out.
