8.3 Vertical Scaling
8.3.1 Registers
The vertical scaler implements a weighted running average filter, which requires the initial weights and the
ratio registers to be configured.
Additionally, it is necessary to program the input and output scaling control registers (3A8, 3A9, and 3AC).
Figure 8-2 shows the active and inactive data lines when scaled vertically.
