Note 1: CE# may be asserted any time before or after OE# is asserted. If CE# is asserted after OE#, all timing relative to
OE# asserted will be referenced instead to the time CE# was asserted.
Note 2: CE# may be negated any time before or after OE# is negated. If CE# is negated before OE#, all timing relative to
OE# negated will be referenced instead to the time CE# was negated.
