15.5.7. Interrupts

This section lists the CoreSight* -related interrupts which should connect to the GIC to allow debug events to trigger interrupts to the cores.

Interrupt Source Interrupt Name Description
DSU CTIIRQ[1] The DSU’s Debug Block CTIIRQ[PE:0] output (and CTIIRQACK[PE:0]) connects from the DSU to the GIC 600 to allow each Processing Element (PE) CTI to generate an interrupt for its particular core.
CTIIRQ[0]
ETR bufintr The CoreSight* SOC-600 Embedded Trace Router (ETR) bufintr output connects to an interrupt input on the GIC 600. This allows the ETR to interrupt a CPU when trace buffer management is needed.
