Write Cycle and Clock Parameters
NOTES:
1. All Write cycles are synchronous and referenced from rising CLK.
2. This parameter is measured as a HIGH time above 2.0V and a LOW time below 0.8V.
3. This parameter is guaranteed with the AC Load (Figure 3) by device characterization, but is not production tested.
4. Addresses are stable prior to CLK transition HIGH.
