Valid Data In
*4
*1 : If OE is HIGH during the write cycle, the outputs will remain at high impedance.
*2 : If CE1s goes LOW (or CE2s goes HIGH) coincident with or after WE goes LOW, the output will remain
at high impedance.
*3 : If CE1s goes HIGH (or CE2s goes LOW) coincident with or before WE goes HIGH, the output will remain
at high impedance.
*4 : Because I/O signals may be in the output state at this Time, input signals of reverse polarity must not be
applied.
