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