Notes:
1.
A write occurs during the overlap (t
WP
) of low CS1# and low WE#. A write begins when CS1# goes low and WE# goes low
with asserting UB# or LB# for single byte operation or simultaneously asserting UB# and LB# for double byte operation. A
write ends at the earliest transition when CS1# goes high and WE# goes high. The t
WP
is measured from the beginning of
write to the end of write.
2.
t
CW
is measured from the CS1# going low to the end of write.
3.
t
AS
is measured from the address valid to the beginning of write.
4.
t
WR
is measured from the end of write to the address change. t
WR
is applied in case a write ends with CS1# or WE# going
high.
