+## Debugging support for peripherals
+The debugger component in CLion can show the peripheral registers of the microcontroller when provided an appropriate
+*.svd file describing the peripherals. The description files can be found on the website of the chip vendors, in our

+The microcontroller on our demo board is from the STM32L4x6 family so the STM32L4x6.svd file is necessary. After 
+adding this file to the project root and configuring it in the _Peripherals_ Tab on the debugger view, the actual state 
+of the microcontroller peripherals can be examined.
