PLL/CCK/SCK with Emulator on BF561

As mentioned elsewhere, I'm pretty new with the Blackfin 561...

 

I would like to adjust my CCK and SCK to optimize several issues, including the PPI speed.  I have tried changing the relevant PLL values using the function Set_PLL() provided in the example code (video_in_out in the Booting(C) folder), and it does not seem to work when using the emulator on the EZ-LITE kit.

 

One symptom is that the IDLE instruction is not satisfied until I Break and then Run again.  Even then, the new values do not take.  I disabled the XML reset parameters, but that had no affect.

 

Has anyone else run into this?

 

TIA.
