Notes:
3. X = “Don't Care.” H = Logic HIGH, L = Logic LOW.
4. 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.
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. CE
7. The SRAM always initiates a read cycle when ADSP is asserted, regardless of the state of GW, BWE, or BW
8. 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 Three-State when
9. Table only lists a partial listing of the byte write combinations. Any combination of BW
after the ADSP or with the assertion of ADSC . As a result, OE must be driven HIGH prior to the start of the Write cycle to allow the outputs to three-state. OE is
a don't care for the remainder of the Write cycle
OE is inactive or when the device is deselected, and all data bits behave as output when OE is active (LOW) .
