The higher-power ARM micros have a bunch of debugging tools for program and data tracing, as you would expect. This feature – CoreSight Trace Macrocells – is also found in the lowly ARM Cortex M3 ...

An increasing number of vendors offer 32-bit microcontrollers based on ARM® Cortex®-M processors, and at the same time, there are also new development environments introduced for these microcontroller ...

The number of easily usable and programmable microcontrollers is small, so when selecting one for a project there are only a handful of very popular, well documented chips that most of us reach for.
