28.3.21 Chromakey Target Color Data Register for Blitter (GR_DETCOL)
The register GR_DETCOL sets the target color for chromakey (α data is not set). Since
chromakey processing is performed after format conversion, data should be specified as 5 bits of
DETC_R (R data), 5 bits of DETC_G (G data) and 5 bits of DETC_B (B data).
