C4.2 Cross-trigger inputs and outputs

Outputs from the PMU, the ETM, and the debug subsystem are cross-trigger inputs to the processor CTI. The CTI then generates cross-trigger outputs to other components in the SoC.

Table C4-1 Cross-trigger inputs

CTI input Name Description
0 DBGTRIGGER, pulsed

Pulsed on entry to debug state.

1 PMUIRQ

PMU-generated interrupt.

This signal is the same as nPMUIRQ with inverted polarity.
