AT91Sam9g25-ek PCK0 programming

Hey folks,

I have an issue getting the PCK0 to express a clock signal.
A previous version of our software shows a nice 25MHz signal expressed on the pin, but after upgrading it, I see the pin go High for the duration but never fall to low.

I'm not super familiar with clock programming and am having a hard time deciphering the AT91 documentation (the datasheet). What would make the PCK jump high but not oscillate?
