 * @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.
