Bit Description
LTA[1:0]. Luma timing adjust
allows the user to specify a
timing difference between
chroma and luma samples.
Reserved.
CTA[2:0]. Chroma timing
adjust allows a specified
timing difference between
the luma and chroma
samples.
AUTO_PDC_EN.
Automatically programs the
LTA/CTA values so that luma
and chroma are aligned at
output for all modes of
operation.
SWPC. Allows the Cr and Cb
samples to be swapped.
