It is important that the IO0-IO3 signals be set to high-impedance at or before the falling edge of the first data out clock. At higher
clock speeds the time available to turn off the host outputs before the memory device begins to drive (bus turn around) is diminished.
It is allowed and may be helpful in preventing IO0-IO3 signal contention, for the host system to turn off the IO0-IO3 signal outputs
(make them high impedance) during the last “don’t care” mode cycle or during any dummy cycles.
CS# should not be driven high during mode or dummy bits as this may make the mode bits indeterminate.
