Notes:
1. CE may be delayed up to t_ACC - t_CE after the address transition without impact on t_ACC.
2. OE may be delayed up to t_CE - t_OE after the falling edge of CE without impact on t_CE or by t_ACC -
t_OE after an address change without impact in t_ACC.
3. t_DF is specified from OE or CE wichever occurs first (CL = 5 pF).
4. This parameter is characterized and is not 100% tested.
5. If CE is de-asserted, it must remain de-asserted for at least 50ns during read operations other-
wise incorrect data may be read.
