* 8. A write occurs during the overlap of a low CE! and low WE.
A write begins at the latest transition among= going low and WE going low.
A write ends at the earliest transition among= going high and WE going high. t,, is measured from the
beginning of write to the end of write.
* 9. &,, is measured from the- going low to the end of write.
* 10. t,,, is measured from the address valid to the beginning of write.
* I 1. t,, is measured from the end of write to the address change. twR app lies in case a write ends at?% or WE going
high.
* 12. During this period, I/O pins are in the output state, therefore the input signals of opposite phase to the outputs
must not be applied.
* 13. If CE goes low simultaneously with Wl? going low or after WE going low, the outputs remain in high
impedance state.
* 14. If CE goes high simultaneously with WE going high or before WE going high, the outputs remain in high
impedance state.
