Notes

18. These parameters are guaranteed by design and are not tested.

CE is HIGH.

22. Tested initially and after any design or process changes that may affect these parameters.

of these signals can terminate the operation. The input data setup and hold timing should be referenced to the edge of the signal that terminates the write.
