Inserts source ID signals into the data packet stream so that trace data can be re-associated with its trace source after the data is read back out of the ETB.

Control registers for trace capture and flushing.

Read, write, and data pointers provide access to ETB registers. In addition, the APB interface supports wait states through the use of a PREADYDBG signal output by the ETB.

The APB interface is synchronous to the ATB domain.

Contains the management, control, and status registers for triggers, flushing behavior, and external control.

Controls reads and writes to the Trace RAM.

Provides test access to the Trace RAM.
