In STOPPED state, no trace capture takes place, but data that is still in the trace memory can be read out.
When in STOPPED state:
- In Circular Buffer mode in ETB, ETF, and ETR configurations, except when
streaming, the captured trace can be read out over debug APB.
- In Circular Buffer mode in ETF configuration, a drain can be initiated by
setting the FFCR.DrainBuffer bit.
- In Software Read FIFO mode 1, the remaining contents of the FIFO can be read out
over debug APB.
- In Software Read FIFO mode 2, a functional controller, such as USB, can
directly read the remaining contents of the FIFO directly from the system
The DISABLED state is entered from this state by clearing CTL.TraceCaptEn bit.
Note: The ETR configured for streaming and the ETS do not support reading of
trace data over APB.
