33.4.19 RGB to YCbCr 4:2:2 CSC Coefficient1 Register
HW_LCDIF_CSC_COEFF1 register provides overall control over color space conversion
from RGB to 4:2:2 YCbCr. The equations for the conversion are given by: Y = C0*R +
C1*G + C2*B + Y_offset Cb= C3*R + C4*G + C5*B + CbCr_offset Cr= C6*R + C7*G
+ C8*B + CbCr_offset
This register carries programming information about RGB to YCbCr 4:2:2 CSC.

This register describes the filtering and subsampling scheme to be performed on the chroma components
in order to convert from YCbCr 4:4:4 to YCbCr 4:2:2 space. Note that the following descriptions apply
individually to Cb and Cr.

SAMPLE_AND_HOLD — No filtering, simply keep every chroma value for samples numbered 2n
and discard chroma values associated with all samples numbered 2n+1.
RSRVD — Reserved
INTERSTITIAL — Chroma samples numbered 2n and 2n+1 are averaged (weights 1/2, 1/2) and that
chroma value replaces the two chroma values at 2n and 2n+1. This chroma now exists horizontally
halfway between the two luma samples.
COSITED — Chroma samples numbered 2n-1, 2n, and 2n+1 are averaged (weights 1/4,1/2,1/4) and
that chroma value exists at the same site as the luma sample numbered 2n and the chroma samples
at 2n+1 are discarded.
