NOTES:

1. A write occurs during the overlap of S low and W low.

2. Product sensitivites to noise require proper grounding and decoupling of power supplies during read and write cycles.

3. All write cycle timings are referenced from the last valid address to the first transitioning address.

4. This parameter is sampled and not 100% tested.
