How to use enum instead of three different states?

I have three states for two booleans:

_shouldViewMoveUp = true
_shouldViewMoveDown = false

_shouldViewMoveUp = false
_shouldViewMoveDown = false

_shouldViewMoveUp = false
_shouldViewMoveDown = true

We need to track for both boolean variables wether is false/true when there is changes in the keyword frame. I want to design my code to look better.

I'm not sure how to do it with enum or one boolean. Can you explain how I can make my code tidy or just the way it is right?
