测试系统其实指的是目标板上JTAG扫描链中各个芯片中TAP测试访问端口和边界扫描单元等，nTRST也就是指复位TAP测试访问端口，不复位芯片逻辑。而目标系统就是目标板上除了测试功能以外的正常逻辑了。nRESET连接FPGA的PROG_B（复位配置逻辑电路，但是这时的复位是由上位PC机使用控制软件通过JTAG电缆或控制器来控制...
How should the nTRST pin of JTAG be terminated on the PCB? It is recommended to leave the nTRST pin OPEN. There is no need to terminate by pull-up or pull-down because the nTRST pin is pulled down in the Traveo™ MCU. The recommended diagram is shown below. Note: This KBA...
