+@cindex SWD multi-drop
+The newer SWD devices (SW-DP v2 or SWJ-DP v2) support the multi-drop extension
+of SWD protocol: two or more devices can be connected to one SWD adapter.
+SWD transport works in multi-drop mode if @ref{dap_create,DAP} is configured
+with both @code{-dp-id} and @code{-instance-id} parameters regardless how many
+DAPs are created.
+
+Not all adapters and adapter drivers support SWD multi-drop. Only the following
+adapter drivers are SWD multi-drop capable:
+cmsis_dap (use an adapter with CMSIS-DAP version 2.0), ftdi, all bitbang based.
