Notes:
1.
A write occurs during the S-CS1# and R-WE# asserted overlap (tWP).
– The write begins with the latest transition of S-CS1# and R-WE# going low (R-UB# and/or R-LB# already asserted).
– The write ends at the earliest transition of S-CS1# or R-WE# goes high.
2.
tCW is measured from S-CS1# going low to the end of a write.
3.
tAS is measured from address valid to the beginning of a write.
4.
tWR is measured from the end of a write to the address change; tWR applied if a write ends as S-CS1# or R-WE# goes
high.
