Up to 10 HWBPs, including:
4 precise HWBPs inside DSP core and one of them is
associated with a counter.
2 imprecise HWBPs from AET.
4 imprecise HWBPs from AET which are shared for
watch point.
Up to 4 watch points, which are shared with HWBPs,
and can also be used as 2 watch points with data (32
bits)
Up to 2, Which can also be used as 4 watch points.

ARM:
• Basic Debug
– Execution Control
– System Visibility
• Advanced Debug
– Global Start
– Global Stop
• Advanced System Control
– Subsystem reset via debug
– Peripheral notification of debug events
– Cache-coherent debug accesses
• Security
– Halting on a security violation (by cross-triggering via INTC)
– Memory accesses prevented to secure memory (this is ensured by system level security
mechanism)
• Program Trace
– Program flow corruption
– Code coverage
– Path coverage
– Thread/interrupt synchronization problems
• Data Trace
– Memory corruption
• Timing Trace
– Profiling
• Analysis Actions
– Stop program execution
– Control trace streams
– Generate debug interrupt
