7.7.2 CLIF PLL CONTROL2 REG
The CLKGEN_CLIF_PLL2_CONTROL_REG register contains the CLIF PLL multiplier
and divider values. Changes to CLKGEN_CLIF_PLL2_CONTROL_REG register do not
take effect until a correct CLIF PLL feed sequence has been given. Calculations for the
USB PLL frequency, and multiplier and divider values are found
