Notes:
1. For a detailed definition of read/write, see the Write Table below.
2. An "X" means don't care, "1" means logic high, and "0" means logic low.
3. The OE pin enables the data output but is not synchronous with the clock. All signals of the SRAM are sampled
to the bus clock except for theOE pin.
synchronous
4. On a write cycle that follows a read cycle, OE must be inactive prior to the start of the write cycle to allow write data to set
the SRAM. OE must also disable the output buffer prior to the end of a write cycle to ensure the SRAM data hold timings
are met.
