STM32F107 clocks

Gunnar Bråding


I got a board with the crystal at 25MHz, and need to use the PLL2 as input to the system clock.
I just do not seem to understand the code enough to see how to set the prediv and multiplication for the PLL2
I can choose PLL2 as input to the PLL, and PLL as input to the system clock, but how do set the parameters for PLL2?

Any pointers would be very much appreciated.
