Updated XJTAG software reportedly increases flexibility for easier access to JTAG capabilities of boards and maximum test coverage. Dynamic chain profiling helps initialize boards with multiple JTAG chains, in which a device in one JTAG chain controls power supplies or reset lines for JTAG devices in other chains. During flash programming, can be set up to clock only JTAG data through the chain needed for programming operation. Can remove need to clock hundreds of bits of data per scan; speeds testing/programming. Increases capabilities of XJLink2 JTAG controller.
