I'm a little confused on that. The 24 MHz crystal with PLL gets it up to 600 MHz, right? That's the CPU setting I have selected. 20 MHz is an integer factor of 600 MHz.

I used the following code to get 20 MHz, but when I checked with an oscilloscope, I was down around 18.9 MHz. I'm really not needing anything fancy. I used the same method to get to 10 MHz and that was right on. I've been browsing the forum...
