DATA OUT
ADDRESS
1. WE must be high during all address transitions.
2. A write occurs during the overlap (T
3. T
of the write cycle.
4. If the CS low transition occurs simultaneously with, or after, the WE low transition, the output remains in
the high impedance state.
5. DATA OUT is the write data of the current cycle, if selected.
6. DATA OUT is the read data of the next address,if selected.
