14 Data Watchpoint and Trace (DWT)
The EM35x integrates the standard ARM
support for profiling and debugging functionality. The DWT offers the following features:
Apart from exception tracing, DWT functionality is counter- or comparator-based. Watchpoint and data trace
support use a set of compare, mask, and function registers. DWT-generated events result in one of two
actions:
When exception tracing is enabled, the DWT emits an exception trace packet under the following conditions:
The DWT is designed for use with advanced profiling and debug tools, available from multiple vendors.
Altering DWT configuration may conflict with the operation of advanced profiling and debug tools.
For further information on the DWT, contact Ember support for the ARM
Manual, the ARM
Reference Manual, and the ARM

Exception trace support
Instruction cycle count calculation support
Generation of a hardware event packet. Packets are generated and combined with software events and
timestamp packets for transmission through the ITM/TPIU.
A core halt – entry to debug state.
Exception entry (from thread mode or pre-emption of a thread or handler).
Exception exit when exiting a handler.
Exception return when re-entering a pre-empted thread or handler code sequence.
