Notes

12.These characteristic pertain to the TAP inputs (TMS, TCK, TDI and TDO). Parallel load levels are specified in the Electrical Characteristics table.

13.Overshoot: VIH(AC) < VDDQ + 0.35V (Pulse width less than tCYC/2), Undershoot: VIL(AC) >0.3V (Pulse width less than tCYC/2).

14.All voltage refer to ground.
