Notes
11.These characteristics pertain to the TAP inputs (TMS, TCK, TDI, and TDO). Parallel load levels are specified in the Electrical Characteristics Table.
12.Overshoot: VIH(AC) < VDDQ + 0.35V (Pulse width less than tCYC/2), Undershoot: VIL(AC) > −0.3V (Pulse width less than tCYC/2).
13.All voltage referenced to ground.
