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 BW
[A:D]
, and WE. See Truth Table for Read/Write.
4. When a Write cycle is detected, all I/Os are three-stated, even during Byte Writes.
5. The DQ 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 three-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 DQ
s
= Three-state when OE is inactive
or when the device is deselected, and DQ
s
= data when OE is active.
