Select Run> Enable Branch Trace Coverage for DTU8. Since a confirmation dialog will be displayed, check the contents and click the [Yes] button. Coverage measurement starts when you set a breakpoint at the point you want to break and start execution. When the program execution breaks, you can check the coverage result by clicking the [Calc.] button in the [Status] window. However, each time a trace overflow occurs, breaks and trace information are acquired, and then re-execution is repeated, so the program execution time becomes extremely long.
