MultiPurpose pin jitter on ADAU144x

I'm finding that I can't get a stable fast (10kHz) square wave out of the MultPurpose pins on my ADAU1445. My scope is telling me it's rock solid 10kHz but I see it scooting around. When I use the pin without a core pull-up I see some sort of signal rippling through it.

 

I've attached a test project.
