TM4C123BH6PZ: Self Clocking maximum speed question

Question:

I see this processor can run with its own internal oscillator.. does that run at the max speed of the part.. or??

From what I can tell from the datasheet - the maximum self-clocking speed is 16MHz (please confirm).

And the maximum external crystal speed is 25MHz...

So it I think it means, no, it can't run at its full speed capability with self clocking.

Thanks!
