3.6.1 IEEE 1149.1 AC Timing Specications
The five JTAG signals are; TDI, TDO, TMS, TCK, and TRST. Unless otherwise noted, JTAG specifications
are referenced to GND and OVDD. The JTAG I/Os are powered by OVDD.

Notes:
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 specication guaranteed by characterization and not tested.
