license for CCS release 4.x had an SRP of US$1,995.00 and a microcontroller-only license was US$495.00. This microcontroller license covered all MSP430, Stellaris and C2x devices. A full license for CCS releases 5.x and 6.x has an SRP of US$495.00 and the microcontroller-only license ceased to exist. Starting in September 2016, the floating license model ceased to exist. For CCS release 7.x the paid license ceased to exist. The software and all its components are distributed with a TSPA license. The free license model was also retrofitted to all public CCS releases since v4. For all releases an annual paid subscription fee was required to grant updates for upcoming major releases. Starting in August 2015, the concept of subscription fee ceased to exist. JTAG Debug probe support Historically CCS supported only JTAG debug probes from TI - also called XDS emulators. The XDS510-class and the more advanced XDS560-class emulators are supported across all releases, but the new low-cost XDS100-class emulator started to be supported starting with the latest patches to release 3.3. Releases 4.x added support for an updated design of the existing XDS100-class emulator (called XDS100v2) and, in release 4.2, added support for an updated design of the XDS560-class emulator (called XDS560v2). Release 5.2 added support for the new XDS200-class emulators. Up until release 4.x, CCS supported only XDS emulators. With the integration of MSP430 and Stellaris microcontrollers, support was added for their respective JTAG debug probes: MSP-FET430 (both parallel and USB versions) and ICDI. Release 5.x also saw the introduction of Beta support for J-Link JTAG debug probes from Segger. Release 6.0.x saw the introduction of the new MSP-FET debug probe for MSP430 devices and the new XDS200-class of debug probes for processors. Release 6.1.x saw the introduction of the new XDS110-class of debug probes for processors. It also saw the migration to full production support for J-Link JTAG debug probes from Segger. Release 7.x saw the integration of J-Link JTAG debug probes from Segger directly in the CCS installer. It is also the first release to support the standalone version of XDS110. 64-bit releases do not support Spectrum Digital XDS510USB JTAG debuggers.
