 J-Link / J-Trace can handle multiple devices in the scan chain. This applies to hardware where multiple chips are connected to the same JTAG connector. As can be seen in the following figure, the TCK and TMS lines of all JTAG device are connected, while the TDI and TDO lines form a bus. J-Link / J-Trace can handle multiple devices in the scan chain.
