TIMING WAVEFORM OF WRITE CYCLE(3)
(CS

Controlled)
NOTES
(WRITE CYCLE)
1. A write occurs during the overlap of a low CS
1
and a high CS
2
low WE. A write begins at the latest transition among CS
1
going low
CS
2
going high and WE goes low. A write ends at the earliest transition among CS
1
going high ,CS
2
going low and WE going high
tWP is measured from the beginning of write to the end write.
2.
t
CW
is measured from the later of CS
1
going low or CS
2
going high 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 or write to the address change.
t
WR1
applied in case a write ends at CS
1
or WE going high,
t
WR2
applied in case a
write ends at CS
2
going to low.
