Configuration of the Software-only Debugger

Debug commands entered via the TRACE32 FrontEnd are converted by the TRACE32 USB Debug BackEnd into JTAG commands and wrapped into the DCI protocol. The DCI packets are sent to the target with the help of libusb.

The DCI bridge on the target side unwraps the DCI packets and passes the JTAG commands to the appropriate TAP/CPU.
