The DWT provides watchpoints, data tracing, and system profiling for the processor. A full DWT contains four comparators that can be configured as any of the following:
The first comparator, DWT_COMP0, can also compare against the clock cycle counter, CYCCNT. The second comparator, DWT_COMP1, can be used as a data comparator.
A reduced DWT contains one comparator that can be used as a watchpoint or as a trigger. A reduced DWT does not support data matching.
The DWT contains counters for the following:
The DWT generates PC samples at defined intervals and interrupt event information. The DWT can also provide periodic requests for protocol synchronization to the ITM and the TPIU.
