1. All voltages referenced to VSS (GND).
2. Worst case address switching.
3. ICC is dependent on output loading and cycle rates.

7. At any given temperature and voltage condition,
tHZCS, is less than tLZCS, and tHZWE is less than tLZWE.
8. WE\ is HIGH for READ cycle.
9. Device is continuously selected. Chip selects and
output enable are held in their active state.
10. Address valid prior to or coincident with latest
occurring chip enable.
11. t = READ cycle time.

12. Chip enable (CS\) and write enable (WE\) can initiate
and terminate a WRITE cycle.
13. I is for full 32 bit mode.
