The Advanced Event Trigger (AET) unit has the capability to generate the debug actions based on events detected by instruction and data bus comparators or by auxiliary event detectors to manage:
- 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 address, address ranges, or data values that can generate events such as halting the processor or triggering the trace captures.
- Counters: count the occurrence of an event of cycles for performance monitoring.
- State Sequencing: allows combinations of hardware program breakpoint and data Watchpoints to precisely generate events for complex sequences.
