These bits select the pre-divide value of the PLL reference clock. When set to any non-zero
value, the reference clock will be divided by the value in PLLM4–0. When set to ‘00000b’,
the reference clock will be divided by 32.
These bits select the multiplication factor of the divided PLL reference clock. When set to
any non-zero value, the multiplication factor will be equal to the value in PLLN7-0. When set
to ‘00000000b’, the multiplication factor will be equal to 256.
