VIL (min.) = -1.0V for pulse width less than tCYC/2, or 5ns, whichever is less. 2. VIH (max.) = VDDQ + 1.0V for pulse width less than tCYC/2 or 5ns, whichever is less. 3. To select operation at 3.3V levels on the I/Os and controls of a given port, the OPT pin for that port must be set to VDD (2.5V), and VDDQX for that port must be supplied as indicated above.
