1. W is high for read cycle.
2. All timings are referenced from the last valid address to the first transitioning address.
3. Addresses valid prior to or coincident with E going low.
4. At any given voltage and temperature, t EHQZ (max) is less than t ELQX (min), and t GHQZ (max) is less than t GLQX (min), both for a given device
5. Transition is measured
6. This parameter is sampled and not 100% tested.
7. Device is continuously selected (E = V IL , COE0 = V IL ).
8. Applies to MPC2107.
