(1) Dual Layer OSD
M37271MF-XXXSP has 2 layers; layer 1 and layer 2. These layers
display the OSD for controlling TV and the closed caption display at
the same time and overlayed on each other.
Each block can be assigned to either layer by bits 6 and 5 of the
block control register (refer to Figure 53). For example, only when
both bits 5 and 6 are “1,” the block is assigned to layer 2. Other bit
combinations assign the block to layer 1.
When a block of layer 1 is overlapped with that of layer 2, a screen is
combined (refer to Figure 55) by bits 7 and 6 of the OSD control
register (refer to Figure 52).
Note:
When using the dual layer OSD, note Table 12.

Note:
For the pre-divide ratio of the layer 2, select the same as the layer 1’s ratio by bit 6 of the clock control register.
