Notes:

2.X=”Don't Care.” H = Logic HIGH, L = Logic LOW. CE stands for ALL Chip Enables active. BWX = L signifies at least one Byte Write Select is active, BWX = Valid signifies that the desired byte write selects are asserted, see Write Cycle Description table for details.

3.Write is defined by BW[A:B], and WE. See Write Cycle Descriptions table.

4.When a write cycle is detected, all I/Os are tri-stated, even during byte writes.

5.The DQ and DQP 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 tri-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 and DQP[A:B] = tri-state when OE is inactive or when the device is deselected, and DQs and DQP[A:B] = data when OE is active.
