+@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.
@subsection SPI Transport
@cindex SPI
The @command{dap} command group supports the following sub-commands:
+@anchor{dap_create}
@deffn {Command} {dap create} dap_name @option{-chain-position} dotted.name configparams...
Declare a DAP instance named @var{dap_name} linked to the JTAG tap
@var{dotted.name}. This also creates a new command (@command{dap_name})
register during initial examination and when checking the sticky error bit.
This bit is normally checked after setting the CSYSPWRUPREQ bit, but some
devices do not set the ack bit until sometime later.
+
+@item @code{-dp-id} @var{number}
+@*Debug port identification number for SWD DPv2 multidrop.
+The @var{number} is written to bits 0..27 of DP TARGETSEL during DP selection.
+To find the id number of a single connected device read DP TARGETID:
+@code{device.dap dpreg 0x24}
+Use bits 0..27 of TARGETID.
+
+@item @code{-instance-id} @var{number}
+@*Instance identification number for SWD DPv2 multidrop.
+The @var{number} is written to bits 28..31 of DP TARGETSEL during DP selection.
+To find the instance number of a single connected device read DP DLPIDR:
+@code{device.dap dpreg 0x34}
+The instance number is in bits 28..31 of DLPIDR value.
