Hello @sholojda 

CoreDebug and DWT registers are part of the ARM Cortex-M3 and Cortex-M4 core peripherals, you can read about it in the ARM Cortex-M3 and Cortex-M4 technical reference manuals.

For CM4: Cortex-M4 Technical Reference Manual

For CM3: Cortex-M3 Technical Reference Manual

Hi,

This is about the core -- read at ARM : (search for the core you want to know more about...)
