Notes on InputTiming:
1. When a set-up time is specified between an input and a clock, the set-up time
is the time in nanoseconds from the 1.4 Volt point of the input to the 1.4 Volt
point of the clock.
2. When a hold time is specified between an input and a clock, the hold time is
the time in nanoseconds from the 1.4 Volt point of the clock to the 1.4 Volt
point of the input.
3. Parameter guaranteed by design, not production tested.
4. Parameter guaranteed by characterization, not production tested.
