+@deffn {Config Command} {ft232r_vid_pid} @var{vid} @var{pid}
+The vendor ID and product ID of the adapter. If not specified, default
+0x0403:0x6001 is used.
+@end deffn
+
+@deffn {Config Command} {ft232r_serial_desc} @var{serial}
+Specifies the @var{serial} of the adapter to use, in case the

+the host. If not specified, serial numbers are not considered.

@deffn {Interface Driver} {remote_bitbang}
Drive JTAG from a remote process. This sets up a UNIX or TCP socket connection
with a remote process and sends ASCII encoded bitbang requests to that process
Use this option with systems where multiple, independent cores are connected
to separate access ports of the same DAP.

The event can be also used to set up the target so it is possible to probe flash.
Probing flash is necessary during GDB connect if you want to use

+@section ARM Cross-Trigger Interface
+@cindex CTI
+
+The ARM Cross-Trigger Interface (CTI) is a generic CoreSight component
+that connects event sources like tracing components or CPU cores with each
+other through a common trigger matrix (CTM). For ARMv8 architecture, a
+CTI is mandatory for core run control and each core has an individual
+CTI instance attached to it. OpenOCD has limited support for CTI using
+the @emph{cti} group of commands.
+
+@deffn Command {cti create} @var{cti_name} -chain-position @var{tap_name} -ap-num @var{apn} -ctibase @var{base_address}
+Creates a CTI object @var{cti_name} on the JTAG tap @var{tap_name} on MEM-AP
+@var{apn} of the DAP reachable through @var{tap}. The @var{base_address} must match
+the base address of the CTI on the respective MEM-AP. All arguments are
+mandatory. This creates a new command (@command{@var{cti_name}}) which
+is used for various purposes including additional configuration.
+@end deffn
+
+@deffn Command {$cti_name enable} @option{on|off}
+Enable (@option{on}) or disable (@option{off}) the CTI.
+@end deffn
+
+@deffn Command {$cti_name dump}
+Displays a register dump of the CTI.
+@end deffn
+
+@deffn Command {$cti_name write } @var{reg_name} @var{value}
+Write @var{value} to the CTI register with the symbolic name @var{reg_name}.
+@end deffn
+
+@deffn Command {$cti_name read} @var{reg_name}
+Print the value read from the CTI register with the symbolic name @var{reg_name}.
+@end deffn
+
+@deffn Command {$cti_name testmode} @option{on|off}
+Enable (@option{on}) or disable (@option{off}) the integration test mode
+of the CTI.
+@end deffn
+
+@deffn Command {cti names}
+Prints a list of names of all CTI objects created. This command is mainly
+useful in TCL scripting.
