Performance Monitor Unit11.7 InterruptsThe Cortex-A15 MPCore processor asserts the nPMUIRQ signal when interrupt is generatedby the PMU. You can route this signal to an external interrupt controller for prioritization andmasking. This is the only mechanism that signals this interrupt to the processor.Interrupt is also driven as a trigger input to the CTI. See Chapter 13 Cross Trigger for moreinformation.ARM DDI 0438I Copyright © 2011-2013 ARM. All rights reserved. 11-18ID062913Non-Confidential
Performance Monitor Unit11.8 Exporting PMU eventsThis section describes exporting of PMU events in:• External hardware.• Debug trace hardware.11.8.1 External hardwareIn addition to the counters in the processor, some of the events that table describes are exportedon the PMUEVENT bus and can be connected to external hardware.11.8.2 Debug trace hardwareSome of the events that tables describes are exported to the PTM unit, other external debug, ortrace hardware, to enable the events to be monitored. See Chapter 12 Program Trace Macrocellland Chapter 13 Cross Trigger for more information.ARM DDI 0438I Copyright © 2011-2013 ARM. All rights reserved. 11-19ID062913Non-Confidential
