Plane n Blending Ratio
Description
The alpha value (α) which is the blend ratio for
plane n should be set.
Blending result = (α × plane n + (H'100 − α) ×
lower plane)/ H'100
Note: Blending result, α, plane n, and lower
Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Plane n Display Size X
The horizontal-direction display size of plane n
should be set in dot clock units.
Note: When YC is set by the PnDDF bit in
