A debugger:
programs the macrocell through its AMBA Peripheral Bus (APB) interface. In a CoreSight system, the APB interface connects to the Debug APB bus.
collects trace data through the AMBA Trace Bus (ATB).
The other external connections to the ETM-A5 are:
0-4 external inputs
0-2 external outputs
a 30-bit extended external input bus.
See Configurable options for more information about the external inputs and external outputs.
In a SoC the ETM-A5 connects to the Cortex-A5:
ETM interface.
Performance Monitoring Unit (PMU). The PMU EVNTBUS signals connect directly to the ETM-A5 extended external interface bus signals
Interfaces describes the ETM-A5 interfaces in more detail.
