On-chip debug and trace events can be exported to external equipment through the debug (trace) port of the device. The following exportable debug events and trace sources are supported:
Note that not all debug and trace features can be supported concurrently because of the limited number of pins allocated to debug. Thus, multiplexing among debug and trace sources is implemented. The configuration and the debug/trace source selection occur through the DRM module embedded in the debug subsystem.
Table 33-2 describes the trace port signals.

The emu[19:0] pins are shared with other functional (application) pins on the device boundary. To use the emu[19:0] pins, the user must program the device application pin manager (Control Module) appropriately. For more information, see Chapter 18, Control Module.
