CLK_VCO is divided by this integer, valid from 1 ..
31.
1 recommended for high freq reference
8 recommended for low freq reference
FLL integer multiplier N for CLK_REF
FLL fractional multiplier K for CLK_REF. This is only
used if FLL_FRAC is set.
Low frequency reference locking
0 = High frequency reference locking (recommended
for reference clock > 48kHz)
1 = Lock frequency reference locking (recommended
for reference clock <= 48kHz)
Fractional enable
0 = Integer Mode
