19. Display Unit (DU)
Table 19.11 RGB888 Bit Configuration in Each Display Data Format
When the format of display data for α blending or EOR operation is 8 bits/pixel, after selection in
advance of the color palette to be used, the α blending or EOR operation on/off should be
specified. At this time, when both planes for α blending or for EOR operation have the same color
palette selected (color palette contention), only the specified plane is displayed, with no α
blending or EOR operation performed. When display of all lower planes is turned off, the
specified plane is displayed. That is, blending or EOR operation of the specified plane with the
display data specified in BPOR is not performed.
α Blending: In α blending, blending processing is performed according to the alpha (α) value set
by the PnALPHA bits in PnALPHAR, the alpha (α) value set by the blend ratio bits in the color
palette, or the alpha (α) value of the input display data.
Notes: 1. In the above formula, the blending result, α, the specified plane, and the lower plane

The priority is set in DPPR.
2. When 0 is set as the alpha value, only the lower plane is displayed.
3. Approximation compensation is not performed. Alpha value is equal to H'FF, specified
