Notes: 1. CEF (CEE) may be delayed up to tACC - tCE after the
address transition without impact on tACC.
2. OE may be delayed up to tCE - tOE after the falling
edge of CEF (CEE) without impact on tCE or by
tACC - tOE after an address change without impact on
tACC.
3. tDF is specified from OE or CEF (CEE) whichever occurs first
(CL = 5 pF).
4. This parameter is characterized and is not 100% tested.
