Switching Waveforms
Read Cycle No. 2 (OE Controlled)
Write Cycle No. 1 (WE Controlled)
Notes:
15. Address valid prior to or coincident with CE
16. Data I/O is high-impedance if OE = V
17. If CE
18. During the DON'T CARE period in the DATA I/O waveform, the I/Os are in output state and input signals should not be applied.
