1. CE# may be asserted any time before or after OE# is asserted. If CE# is asserted after OE#, all timing relative to when OE# was asserted
will be referenced to the time CE# was asserted.
2. CE# may be negated any time before or after OE# is negated. If CE# is negated before OE#, all timing relative to when OE# was negated
will be referenced to the time CE# was negated.
only support VCC=2.7-3.6V.
