Write Cycle3
(UB#, LB# Controlled)(See Note 4)
Note:
1. WE# remains HIGH for the read cycle.
2. If CE# goes LOW with or after WE# goes LOW, the outputs will remain at high impedance.
3. If CE# goes HIGH coincident with or before WE# goes HIGH, the outputs will remain at high impedance.
4. If OE# is HIGH during the write cycle, the outputs will remain at high impedance.
5. Because I/O signals may be in the output state at this time, input signals of reverse polarity must not be
applied.
