No, the EE-68 application note describing the ADI-recommended JTAG circuitry applies to all of ADI's processor portfolio up to and including the ADSP-BF60x family of dual-core Blackfin processors.
Beginning with the ADSP-BF70x Blackfin+ processors and carried forward to the recently announced ADSP-2158x/SC58x dual-core SHARC+ processors, the debug unit infrastructure block was changed to also support ARM technology. As such, an equivalent application note is currently being developed in support of these and future devices.
