Write Cycle (1) (WE# CLOCK, OE#=”H” while writing)
Note 14. t
WP
is the interval between write start and write end.
A write starts when both of CS# and WE# become active.
A write is performed during the overlap of a low CS# and a low WE#.
A write ends when any of CS# or WE# becomes inactive.
15. t
OHZ
and t
WHZ
are defined as the time when the I/O pins enter a high-impedance state and are not referred to
the I/O levels.
16. This parameter is sampled and not 100% tested.
17. During this period, I/O pins are in the output state so input signals must not be applied to the I/O pins.
