(UB, LB Controlled)
NOTES
(WRITE CYCLE)
1. A wri
t
e occurs during the overlap(t
WP
) of low CS and low WE. A write begins when CS 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 transi-
tion when CS 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 CS going low to 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 or write to the address change.
