2. X = Do Not Care, H = Logic HIGH, L = Logic LOW.
3. WRITE = L when any one or more Byte Write enable signals and BWE = L or GW = L. WRITE = H when all Byte write enable signals, BWE, GW = H.
4. The DQ pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.
6. OE is asynchronous and is not sampled with the clock rise. It is masked internally during write cycles. During a read cycle all data bits are tri-state when OE is inactive
5. The SRAM always initiates a read cycle when ADSP is asserted, regardless of the state of GW, BWE, or BW
ADSP or with the assertion of ADSC. As a result, OE must be driven HIGH before the start of the write cycle to allow the outputs to tri-state. OE is a do not care for
the remainder of the write cycle.
or when the device is deselected, and all data bits behave as outputs when OE is active (LOW).
