1. V IL (min.) = -1.0V for pulse width less than t CYC /2 or 5ns, whichever is less.
2. V IH (max.) = V DDQ + 1.0V for pulse width less than t CYC /2 or 5ns, whichever is less.
3. To select operation at 2.5V levels on the I/Os and controls of a given port, the OPT
pin for that port must be set to V ss (0V), and V DDQX for that port must be supplied as indicated
above.
