1. All outputs are measured from the midpoint voltage of the falling/rising edge of TCLK to the midpoint of the signal in ques-
2. TRST is an asynchronous level sensitive signal. The setup time is for test purposes only.
3. Non-JTAG signal input timing with respect to TCK.
4. Non-JTAG signal output timing with respect to TCK.
5. Guaranteed by design and characterization
