The PLL/AUXPLL is responsible for synthesizing an output frequency from the input clock (from the oscillator); Figure 3-10 shows a simple block diagram of the PLL/AUXPLL. The PLL/AUXPLL divides the reference input for a lower frequency input into the PLL/AUXPLL by (REFDIV+1). Then multiplies this internal frequency by IMULT to get the VCO output clock. The PLL/AUXPLL output is divided by (ODIV+1) to generate PLLRAWCLK/AUXPLLRAWCLK which is further divided by SYSCLKDIVSEL.PLLSYSCLKDIV/AUXCLKDIVSEL.AUXPLLDIV to generate PLLSYSCLK/AUXCLK
