Trace and Profile

The P&E TraceLink allows the user to capture real-time external trace information without having to stop or disturb the running application. This allows the user to see the real-time execution of their code by continuously recording the processor events. For external trace captures, the P&E TraceLink supports ETM trace. The Kinetis chip must have Trace_CLKOUT and Trace_D[3:0] pins to support ETM trace. Chips without these pins can still be debugged by the TraceLink within CodeWarrior
