Figure 3-10 SRAM compatible address timing
Note
If ALE is to be used to change address timing, then you must tie APE HIGH. Similarly,
if APE is to be used, ALE must be tied HIGH.
You can obtain better system performance when the address pipeline is enabled with
APE HIGH. This allows longer time for address decoding.
