Notes:
1. All outputs are measured from the midpoint voltage of the falling/rising edge of t
2. The symbols used for timing specifications follow the pattern of t
3. TRST is an asynchronous level sensitive signal. The setup time is for test purposes only.
4. Non-JTAG signal input timing with respect to t
5. Non-JTAG signal output timing with respect to t
6. Guaranteed by design and characterization.
The output timings are measured at the pins. All output timings assume a purely resistive 50-Ω load (see
Time-of-flight delays must be added for trace lengths, vias, and connectors in the system.
