Well, it's not enough to understand the CE is "somekind of a enable pin."

What does it do? How does the part behave with that pin is HI? How does it behave with the pin is LO?

Read the data sheet -- they have a section devoted to the CE pin.

Take note that there are different variants of this part depending on the polarity and existence of a passive pull-up/pull-down on the CE pin. Your schematic doesn't say which variant it is for.

Well, particularly since this is Homework Help and not Homework Done For You, what do YOU think it does based on YOUR understanding of the data sheet?
