2.X = “Don't Care.” H = Logic HIGH, L = Logic LOW. BWx = 0 signifies at least one Byte Write Select is active, BWx = Valid signifies that the desired Byte Write Selects are asserted, see Truth Table for details.

3.Write is defined by BW[A:D], and WE. See Truth Table for Read/Write.

4.When a Write cycle is detected, all I/Os are three-stated, even during Byte Writes.

5.The DQ pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.

6.CEN = H, inserts wait states.

7.Device will power-up deselected and the I/Os in a three-state condition, regardless of OE.

8.OE is asynchronous and is not sampled with the clock rise. It is masked internally during Write cycles. During a read cycle DQs = Three-state when OE is inactive or when the device is deselected, and DQs = data when OE is active.
