Write Cycle (3) (CS# CLOCK)
Note 24. t
WP
is the interval between write start and write end.
A write starts when all of (CS#), (WE#) and (one or both of LB# and UB#) become active.
A write is performed during the overlap of a low CS#, a low WE# and a low LB# or a low UB#.
A write ends when any of (CS#), (WE#) or (one or both of LB# and UB#) becomes inactive.

Note 26. Typical parameter indicates the value for the center of distribution at 3.0V (Ta=25ºC), and not 100% tested.
27. CS# controls address buffer, WE# buffer, OE# buffer, LB# buffer, UB# buffer and I/O buffer. If CS# controls
data retention mode, Vin levels (address, WE#, OE#, LB#,UB#, I/O) can be in the high-impedance state.
