11.4.7.1. Cross Trigger Interface

CTIs allow trigger sources and sinks to interface with the ECT. Each CTI supports up to eight trigger inputs and eight trigger outputs, and is connected to a CTM. The CTI Connections table shows the relationship of trigger inputs, trigger outputs, and CTM channels of a CTI.

Figure 46. CTI Connections

The following figure shows the eight potential trigger input and trigger output connections that are supported.

The HPS debug system contains the following CTIs:
  • CTI—performs cross triggering between the STM, ETF, ETR, and TPIU.
  • FPGA-CTI—exposes the cross-triggering system to the FPGA fabric.
  • CTI-0 and CTI-1—reside in the MPU debug subsystem. Each CTI is associated with a processor and the processor’s PTM.
  • L3-CTI—allows cross triggering with L3 interconnect.
