Note:
All AC timing signals observe the following guidelines for determining setup and hold times:
(a) High level signal's reference level is input high and
(b) low level signal's reference level is input low. Ref. to the AC testing condition.
(c) Exclude 00H pre-program prior to erasure. (In the pre-programming step of the embedded erase algorithm, all bytes are
programmed to 00H before erasure
