The digital loop filter coefficients (α, β, γ, and δ) have the general form: x(2
The value of the linear component (x) constitutes a fraction, where 0 ≤ x < 1. The exponential component (y) is an integer. See the Calculating the Digital Filter
Coefficients section for details.
The value stored in the R divider register yields an actual divide ratio of one more than the programmed value.
