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 9-9). Time-of-flight delays must be added for trace lengths, vias and con-
nectors 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.
