Can i connect unsed jtag to gnd
WebXJTAG’s XJLink2 controller can connect to up to four JTAG connectors on a board. Connector design. When specifying the signal positions on the JTAG connector it is important to consider possible crosstalk/interference issues. Interleaving active signals with ground connections will minimize these effects. ... (or ‘soft GND’) pins of the ... WebJTAG is not JUST a technology for programming FPGAs/CPLDs. The debug and programming tools commonly associated with JTAG only make use of one aspect of the underlying technology – the four-wire JTAG communications protocol. These four signals, collectively known as the Test Access Port or TAP, are part of IEEE Std. 1149.1.
