2.4 Advanced Event Triggering (AET)
The C674x megamodule supports advanced event triggering (AET). This capability can be used to debug
complex problems as well as understand performance characteristics of user applications. AET provides
the following capabilities:
• Hardware Program Breakpoints: specify addresses or address ranges that can generate events such
as halting the processor or triggering the trace capture.
• Data Watchpoints: specify data variable addresses, address ranges, or data values that can generate
events such as halting the processor or triggering the trace capture.
• Counters: count the occurrence of an event or cycles for performance monitoring.
• State Sequencing: allows combinations of hardware program breakpoints and data watchpoints to
precisely generate events for complex sequences.
