12.11.1 Triple Layer OSD
Three built-in layers of display screens accommodate triple display
of channels, volume, etc., closed caption, and sprite displays within
layers 1 to 3.
The layer to be displayed in each block is selected by bit 0 or 1 of the
OSD control register 2 for each display mode (refer to Figure 12.11.7).
Layer 3 always displays the sprite display.

When the layer 1 block and the layer 2 block overlay, the screen is
composed (refer to Figure 12.11.5) with layer mixing by bit 6 or 7 of
the OSD control register 1, as shown in Figure 12.11.3. Layer 3
always takes display priority of layers 1 and 2.
Notes 1: When mixing layer 1 and layer 2, note Table 12.11.2.
2: OUT2 is always ORed, regardless of values of bits 6, 7 of the OSD
control register 1. And besides, even when OUT2 (layer 1 or layer 2)
overlaps with SPRITE display (layer 3), OUT2 is output.

1.5TC can be selected only when: layer 1’s pre-divide ratio = ! 2
AND layer 1’s horizontal dot size = 1TC.
As this time, vertical dot size is the same as layer 1.

However, when dot size is 2TC ! 2H or 2TC ! 3H, set difference between vertical display position of
layer 1 and that of layer 2 as follows.
2TC ! 2H: 2H Units
3TC ! 3H: 3H Units
