Notes:
9. Device is continuously selected. OE, CE1 = VIL. CE2 = VIH.
10. WE is HIGH for read cycle.
11. Data I/O is High Z if OE = VIH, CE1 = VIH, or WE = VIL.
12. Address valid prior to or coincident with CE1 transition LOW and CE2 transition HIGH.
13. During this period, the I/Os are in the output state and input signals should not be applied.
