| * Check if a debugger is connected (and debug session activated). |
| * |
| * @details |
| * Used to make run-time decisions depending on whether or not a debug session |
| * has been active since last reset, i.e., 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. |
