3.2.1. Scaler Adjustment
In case of linear scaling, most of the scaler registers
need not be set. Only the scaler mode, active video
length, and the fixed scaler increments (scinc1/scinc2)
must be written.
The adjustment of the scaler for nonlinear scaling
modes should use the parameters given in Table 3–4.
