TIMING WAVEFORM OF WRITE CYCLE(3)
(UB, LB Controlled)
NOTES
(WRITE CYCLE)
1. A wri
t
e occurs during the overlap(t
WP
) of low CS
1
and low WE. A write begins when CS
1
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 tran-
sition when CS
1
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
1
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.
t
WR
applied in case a write ends as CS
1
or WE going high.
