Notes:
1. A write cycle occurs during the overlap of
CS
= "L" and
WE
= "L".
2.
OE
may be either of "H" or "L" in the write cycle.
3. t
AS
is specified from
CS
= "L" or
WE
= "L", whichever occurs last.
4. t
WP
is an overlap time of
CS
= "L" and
WE
= "L".
5. t
WR
, t
DS
and t
DH
are specified from
CS
= "H" or
WE
= "H", whichever occurs first.
6. t
WHZ
is specified by the time when DATA output is floating, not defined by the
output level.
7. When I/O pins are in the output mode, don't apply the inverted input signal to the
output pins.
