line counter preset: preset value stored in the
line counter on the rising edge of the internal
VSYNC
line counter number of lines: modulo of the
line counter; this counter counts from 1 to
LCNT_NLIN and rolls-over to 1; the
recommended value is the total number of lines
per frame; if value is set to 000h the line counter
uses the value of MEAS_LINES
Description
offset output 1: the new brightness values for
the channel G/Y, e.g. with YC
so OFFSET_OUT1 = 0 0001 0000b = 10h
offset output 2: the new brightness values for
the channel R/V e.g. with YC
C
offset output 3: the new brightness values for
the channel B/U e.g. with YC
C

matrix bypassed: bypasses or not the matrix
and offsets conversion

pixel counter preset: preset value stored in
the pixel counter on the rising edge of the
internal HSYNC
pixel counter number of pixels: modulo of
the pixel counter; this counter counts from 1
to PXCNT_NPIX and rolls-over to 1; the
recommended value is the total number of
pixels per line
so OFFSET_OUT2 = 0 1000 0000b = 80h
so OFFSET_OUT3 = 0 1000 0000b = 80h
