Valid data

Notes: 1. If CS goes low simultaneously with WE going low or after WE going low,

the outputs remain in the high impedance state.

2. Dout is the same phase of the write data of this write cycle.

3. Dout is the read data of next address.

4. If CS is low during this period, I/O pins are in the output state. Therefore, the input

signals of theopposite phase to the output must not be applied to them.
