5. Applicable to A3 to A19 when E1 is kept at Low.
6. Applicable only to A0, A1 and A2 when E1 is kept at Low for the page address access.
7. In case Page Read Cycle is continued with keeping E1 stays Low, E1 must be brought to High within 4µs. In other words, Page
8. Applicable when at least two of address inputs among applicable are switched from previous state.
