7.13. Cycle-accurate tracing

When profiling the execution of critical code sequences, it is often useful if you can observe the exact number of cycles that a particular code sequence takes to execute. To perform this cycle-accurate tracing, you must set bit [12] of the ETMCR to 1, see Main Control Register, ETMCR.
