Notes:
1. X = “Don't Care”, 1 = Logic HIGH, 0 = Logic LOW, CE stands for ALL Chip Enables active. BWx = 0 signifies at least one Byte Write Select is active, BWx =
2. Write is defined by WE and BW
3. When a write cycle is detected, all I/Os are three-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 will power-up deselected and the I/Os in a three-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 DQs and DQP
Valid signifies that the desired Byte Write Selects are asserted, see Write Cycle Description table for details.
OE is inactive or when the device is deselected, and DQs = data when OE is active.
