1. X = “Don't Care”, H = Logic HIGH, L = Logic LOW, CE stands for ALL Chip Enables active. BWx = 0 signifies at least one Byte Write Select is active, BWx = Valid
2. Write is defined by WE and BW
3. When a write cycle is detected, all IOs are tri-stated, even during Byte Writes.
4. The DQ and DQP pins are controlled by the current cycle and the OE signal.
5. CEN = H inserts wait states.
6. Device powers up deselected with the IOs in a tri-state condition, regardless of OE.
7. OE is asynchronous and is not sampled with the clock rise. It is masked internally during Write cycles. During a read cycle DQ
signifies that the desired byte write selects are asserted, see
inactive or when the device is deselected, and DQ
