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.
In QPI Mode (CR2V[6]=1) the Quad I/O instructions are sent 4 bits per SCK rising edge. The remainder of the
command protocol is identical to the Quad I/O commands.
