Notes: 1. A write occurs during the overlap of a low CS and a low WE (t
WP
).
2. t
WR
is measured from the earlier of CS or WE going high to the end of the write cycle.
3. If the CS low transition occurs simultaneously with the WE low transition or after the WE
transition, the output buffers remain in a high-impedance state.
