R/W remains HIGH for the read cycle.
If CE1 (or UB or LB ) goes LOW(or CE2 goes HIGH) coincident with or after R/W goes LOW, the
outputs will remain at high impedance.
If CE1 (or UB or LB ) goes HIGH(or CE2 goes LOW) coincident with or before R/W goes HIGH, the
outputs will remain at high impedance.
If OE is HIGH during the write cycle, the outputs will remain at high impedance.
Because I/O signals may be in the output state at this time, input signals of reverse polarity must not be
applied.
