3.3. Embedded trace support

The ARM922T processor within the stripe incorporates an ARM9 Embedded Trace Macrocell (ETM9). This enables you to carry out real-time debugging by connecting external trace equipment to the core module. To trace program flow, the ETM broadcasts branch addresses, data accesses, and status information through the trace port. Later in the debug process, the complete instruction flow can be reconstructed by the ARM Trace Debug Tools (TDT).
