VREF to Analogue Output Resistance
(Disabled Outputs)
0 = 500Ω from buffered VMID to output
1 = 20kΩ from buffered VMID to output
Analogue enable
0 = FLL disabled
1 = FLL enabled
FLL_OSC_ENA must be enabled before
enabling FLL_ENA. The order is important.
CLK_VCO is divided by this integer, valid
from 1 .. 31.
Value 1 recommended for Reference clock
> 96kHz
Value 8 recommended for Reference clock
< 96kHz
Fractional enable
0 = Integer Mode
1 = Fractional Mode
(Fractional N mode increases digital power
consumption of the FLL)

Low frequency reference locking
0 = Lock achieved after 509 ref clks
(Recommended for Reference clock >
48kHz)
1 = Lock achieved after 49 ref clks
(Recommended for Reference clock <=
48kHz)
