NOTES (WRITE CYCLE)

1. A write occurs during the overlap(tWP) of low CS and low WE. A write begins at the latest transition among CS goes low and

WE goes low. A write ends at the earliest transition when CS goes high and WE goes high. The tWP is measured from the

beginning of write to the end of write.

2. tCW is measured from the CS going low to end of write.

3. tAS is measured from the address valid to the beginning of write.

4. tWR is measured from the end or write to the address change. tWR applied in case a write ends as CS or WE going high.
