    As long as you're HIGH level is over the minimum Vih, and your LOW level is under than min Vil, you're not going to have problem.

    By their notation on the CS pin, it has to be active when low, unless they wouldn't have place a line over it.

    Have a look at Wikipedia for a real-English explanation

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
