Is this supposed to say "maximum" rather than "minimum"?

15MHz. Mostly it can do much better than that and is in fact often run at
32MHz. With a clever driver that runs configuration commands at a low speed
and only the pixel data at the maximum speed the configuration can't be
messed up by transfer errors and the speed is only limited by the amount of
pixel glitches that one is able to tolerate.
