Inserts source ID signals into the data packet stream so that trace data can be re-associated with its trace source. See TPIU formatter and FIFO.

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

The trace out block serializes formatted data before it goes off-chip.

The pattern generator unit provides a simple set of defined bit sequences or patterns that can be output over the Trace Port and be detected by the TPA or other associated Trace Capture Device (TCD). The TCD can use these patterns to indicate if it is possible to increase or to decrease the trace port clock speed. See TPIU pattern generator for more information.
