2.1.9 Debug Event Module overview
The Debug Event Module (DEM) provides debug, trace, and PMU capability.
The DEM is included in the MN and is responsible for the following operations:
- Aggregating watchpoint trigger events from all Debug Watchpoint
Modules (DWMs) that are included in all crosspoints, and optionally asserting the DBGWATCHTRIGREQ signal for a trigger event.
- Time-aligning these trigger events.
- Communicating these trigger events to
System Trace Module (STM).
- Counting PMU
events that are
communicated by other components in the CCN-502.
- Requesting assertion of the INTREQ interrupt signal on overflow of PMU counters.
