NOTES (WRITE CYCLE)

1. A write occurs during the overlap(tWP) of low CS1 and low WE. A write begins when CS1 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 transition when CS1 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 CS1 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 CS1

or WE going high.
