Linear Interpolation (o3925.1 = 0 oder o3925.1 = -1)
With the transmitted position and the position in the previous bus cycle, a straight
of the Y(t)=a*t + b is calculated. The speed within a bus cycle remains constant.
This method is only implemented for the PLL synchronization.
Advantage: Support of a reset value range
Disadvantage: During the transition to a new bus cycle, a speed leap may occur.
