VREF chop oscillator?

The K02 reference manual mentions a chop oscillator but doesn't explain what it is.  A quick Google search doesn't return anything obviously relevant.  I'm not an analog guy and I could only name a handful of oscillator types, and I'm not clear what the oscillator is doing in the VREF module.

 

I'm seeing some weird behavior from VREF and I'd like to better understand how it works.  Is there any documentation on this subject?

 

Thanks,

 

Scott
