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 of CE# asserted.
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 of CE# negated.
