Buffering of clock and signals are recommended whenever the JTAG interface connects to more than one attached device. Buffering of clock is recommended even for single device implementations. For implementation, see the device-specific SK.
If trace operation is used, connect TRC_DATAn signals directly to the emulation connector. All TRC_DATAn signals are pin-MUXed with other signals. Use either trace functionality or a GPMC interface. Short and skew matched connections (board trace) for TRC_DATAn signals are used for trace functionality. The trace signals are on VDDSHV3 Dual-voltage IO group, and can be at a different supply voltage from the other JTAG signals. For additional recommendations on TRC/EMU design and layout, see the Emulation and Trace Headers Technical Reference Manual. A summary is available in the XDS Target Connection Guide.
If boundary scan is used, connect EMU0 and EMU1 pins directly to the JTAG connector.
For proper implementation of the JTAG interface, see the Emulation and Trace Headers Technical Reference Manual and the XDS Target Connection Guide.
