The PL fabric trigger macrocell (FTM) is a feed-through module for the cross-trigger signals to and from the PL. The FTM also provides a GPIO to/from the PL for simple communication. The FTM has the following features.
•A CoreSight component that is compliant with the Arm specification.
•Four trigger inputs and four trigger outputs.
•32-bit general purpose inputs from the PL
•32-bit general purpose outputs to the PL.
•Topology detection for trigger signals using integration mode.
This Figure shows the steps involved in FTM configuration.
