Figure 10-4. Write Cycle Timing Diagram
Timing measurements are referenced to and from a low voltage of 0.8 V
and a high voltage of 2.0 V, unless otherwise noted. The voltage swing
through this range should start outside and pass through the range such
that the rise or fall will be linear between 0.8 V and 2.0 V.
