Conclusion 17
7 Conclusion
This application note presented two techniques to measure the speed of execution of software running on
an SC140 device, using the SC140 Enhanced OnCE. The first technique requires instrumenting the
application code with calls to stopwatch timer routines. The second technique controls the stopwatch timer
within the Metrowerks Code Warrier debugger.
In addition, examples were provided in this application note to demonstrate setting up the SC140 Phase
Lock Loop, and software control of the LED available on the Software Development Platform.
