Notes:
1. All outputs are measured from the midpoint voltage of the falling/rising edge of TCLK to the midpoint of the signal
in question. The output timings are measured at the pins. All output timings assume a purely resistive 50-
Ω load
(see Figure 11). Time-of-flight delays must be added for trace lengths, vias, and connectors in the system.
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.
