The diagram shows only supported (tested) synchronous state transitions. The diagram presumes G is tied Low.
The upper portion of the diagram assumes active use of only the Enable (E

and that ADSP is tied high and ADSC is tied low.
The upper and lower portions of the diagram together assume active use of only the Enable, Write and ADSC control inputs and assumes
ADSP is tied high and ADV is tied low.
