23. When a part with a maximum frequency above 167 MHz is operating at a lower clock frequency, it requires the input timings of the frequency range in which it is operated 

and outputs data with the output timings of that frequency range.

24. This part has a voltage regulator internally; t

POWER

 is the time that the power must be supplied above V

DD

 minimum initially before a read or write operation is initiated.
