5.8.2. Disabling trace

When TraceEnable becomes inactive, tracing stops and the pipeline status changes to WT (Wait) while the FIFO drains. When there is no more data in the FIFO the pipeline status changes to TD (Trace Disabled). This enables the TPA to suppress tracing, and so improve the trace buffer utilization.

Note

In cycle-accurate tracing, TD cycles can correspond to WT cycles. In this case the TPA might still have to capture these cycles. For more information see Cycle-accurate tracing.
