Table 10-68 summarizes the DEBUG core assignment. Emulation suspend output of all the cores are synchronized
to SYSCLK1/6 which is frequency of the slowest peripheral that uses these signals.

10.36.5 Advance Event Triggering (AET)
The device 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.
For more information on the AET, see the following documents in 2.4 ‘‘Related Documentation from Texas
Instruments’’ on page 19.
