* @brief
* Check if a debugger is connected (and debug session activated)
*
* @details
* Used to make run-time decisions depending on whether a debug session
* has been active since last reset, ie using a debug probe or similar. In
* some cases special handling is required in that scenario.
*
* @return
* true if a debug session is active since last reset, otherwise false.
