5.22.3 Embedded Cross Trigger

The Embedded Cross Trigger (ECT) is a modular component that supports the interaction and synchronization of multiple triggering events within a SoC.

The ECT consists of two modules:

  • A (Cross Trigger Interface) CTI. The CTI provides the interface between a component or subsystem and the Cross Trigger Matrix (CTM).
  • A CTM. The CTM combines the trigger requests generated from CTIs and broadcasts them to all CTIs as channel triggers. This enables subsystems to interact, cross trigger, with one another.
