3.5.15.7. Cross Trigger Interface

The Cortex® -A53 processor has a cross trigger interface (CTI) that communicates with ARM's CoreSight module. The CTI enables debug logic, ETM and PMU to interact with each other and with other HPS debugging components including the FPGA fabric. The ETM can export trigger events and perform actions on trigger inputs. Also, a breakpoint in one CPU can trigger a break in the other.
