12.11 Exporting PMU events
This section describes exporting of PMU events in:
• External hardware.
• Debug trace hardware.
12.11.1 External hardware
In addition to the counters in the processor, some of the events that Table 12-28 on page 12-36
describes are exported on the PMUEVENT bus and can be connected to external hardware.
12.11.2 Debug trace hardware
Some of the events that Table 12-28 on page 12-36 describes are exported to the ETM trace unit,
or to the Cross Trigger Interface (CTI), to enable the events to be monitored. See Chapter 13
Embedded Trace Macrocell and Chapter 14 Cross Trigger for more information.
