Hello! While playing a bit with UrJTAG and miscelanous devices it turned out that some devices requires nTRST, in particular ARM TDMI from NXP (LPC family). Because I was developing some application with OpenOCD and it was working fine, I tried to evasdrop the OpenOCD signalling of JTAG. By looking with oscilloscope on nTRST and nSRST lines driven by OpenOCD, they periodicaly turns low and high. What is exact timing of signals these lines gets low and high (what moment/what function)? Is there any good and commonly available document on JTAG timing?
