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 signifies
2. Write is defined by WE and BW
3. When a write cycle is detected, all I/Os are tristated, 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 will power-up deselected and the I/Os in a tristate 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
that the desired byte write selects are asserted, see Write Cycle Description table for details.
