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
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
1 = Fractional Mode
1 recommended in all cases
Select FLL input clock Source
00 = MCLK
01 = DACLRCLK
10 = ADCLRCLK
11 = CLK_32K_REF
Recommended that these are not changed from
default.
FLL fractional multiplier K for CLK_REF. This
is only used if FLL_FRAC is set.
