2.14.2.1. 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 2–7.

4C -

scaler2 window controls see table

5 12-bit registers for control of the nonlinear scaling

this register is updated when the scaler mode register is written
