The R5F core generates several events as part of event bus. That can be monitored by the PMU for debugging.The R5 core event bus only signals event when it is enabled. Non-invasive or invasive debug mode needs to be enabled to enable the PMU counters.
The export of the events to the event bus can be enabled by setting the X bit in the Performance Monitor Control Register of the R5 core. For more details, refer to Arm R5 TRM.
