Been working on setting my clock using the SysCtlClockSet macro and been having some problems understanding the documentation on it. I'm trying to reach a specific clock with the PLL at 400MHz, and dividing by a specific number. I can't understand entireley the parameters of the macro because it always divides the PLL by 2, and then it always uses the RCC register to set the clock frequency. Inside the macro (going to Sysctl.c) you can see what type of changes it does to what registers and it does always change the RCC and RCC2 register but I don't know what parameter to send to use the RCC2 register to select my desired clock. During the reading it repeats different classes of the Stellaris, Firestorm, Fury, etc. What class is the LM4F120H5QR?
Thanks,
