IEEE 1149.1 AC Timing Specications
The table below provides the IEEE 1149.1 (JTAG) AC timing specifications as defined in Figure 9, Figure 10,
Figure 11, and Figure 12. The five JTAG signals are; TDI, TDO, TMS, TCK, and TRST.

Note:
1. TRST is an asynchronous level sensitive signal. Guaranteed by design.
2. Non-JTAG signal input timing with respect to TCK.
3. Non-JTAG signal output timing with respect to TCK.
4. Guaranteed by characterization and not tested.
5. Minimum spec guaranteed by characterization and not tested.
