WRITE CYCLE 2 ( CONTROLLED)
(See Note 4)
Note:
(1)
R/W remains HIGH for the read cycle.
(2)
If CE goes LOW coincident with or after R/W goes LOW, the outputs will remain at high impedance.
(3)
If CE goes HIGH coincident with or before R/W 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.
