Notes:
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 BWX, and WE. See truth table for Read/Write.
4. When a write cycle is detected, all I/Os are tri-stated, even during byte writes.
5. The DQs and DQPX 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 DQPX = Tri-state when OE
is inactive or when the device is deselected, and DQs and DQPX = data when OE is active.
