Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

vco1 Fields

Bit Name Description Access Reset
21:16 denom
Denominator in VCO output frequency equation. For incremental frequency change, if the new value lead to less than 20% of the frequency change, this value can be changed without resetting the PLL. The Numerator and Denominator can not be changed at the same time for incremental frequency changed.
RW 0x1
12:0 numer
Numerator in VCO output frequency equation. For incremental frequency change, if the new value lead to less than 20% of the frequency change, this value can be changed without resetting the PLL. The Numerator and Denominator can not be changed at the same time for incremental frequency changed.
