Logical sum (OR) of
layer 1âs color and
layer 2âs color (See note)
Bit 7 = â0,â bit 6 = â0â
Layer 1âs color has priority
Bit 7 = â0,â bit 6 = â1â
Layer 2âs color has priority
Bit 7 = â1,â bit 6 = â0â
Note: Layer mixing is not logical sum (OR) of colors, but that of each bit of
color pallet register.
Example) When logical sum (OR) is performed on color pallet 1 (00012) and color
pallet 2 (00102), the color set to color pallet 3 (00112) is output, regardless of
color pallets 1 and 2 contents.
