A write occurs during the overlap(t WP) of low CS and low WE. A write begins when CS 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 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 the end of write. 3. tAS is measured from the address valid to the beginning of write. 4. tWR is measured from the end of write to the address change. tWR is applied in case a write ends with CS or WE going high.
