9 Event Status Register, EVENTSTAT

The EVENTSTAT register is used by the system to signal an event to the external debugger.

SoC-600 implements the EVENTSTAT register with top level input dp_eventstatus, connected to an output trigger of a CoreSight Cross-Trigger Interface (CTI) with software acknowledge. This input signal dp_eventstatus coming from CTI trigout is inverted and synchronized in the DP before it goes to the EVENTSTAT register.
