2. Burst sequence order is determined by MODE (0 = linear, 1 = interleaved). BURST operations are optional.
3. CE# represents three signals. When CE# = 0, it represents CE# = 0, CE2# = 0, CE2 = 1.
4. Data coherency is provided for all possible operations. If a READ is initiated, the most current data is used. The most
