Bit Description
CMG[11:8]. Chroma manual gain can
be used to program a desired
manual chroma gain. Reading back
from this register in AGC mode gives
the current gain.
Reserved
CAGT[1:0]. Chroma automatic gain
timing allows adjustment of the
chroma AGC tracking speed.
CMG[7:0]. Chroma manual gain
lower 8 bits. See CMG[11:8] for
description.
LMG[11:8]. Luma manual gain can
be used to program a desired
manual chroma gain or to read back
the actual gain value used.
Reserved
LAGT[1:0]. Luma automatic gain
timing allows adjustment of the
luma AGC tracking speed.
LMG[7:0]. Luma manual gain can be
used to program a desired manual
chroma gain or read back the actual
used gain value.
Reserved
HVSTIM. Selects where within a line
of video the VS signal is asserted.
NEWAVMODE. Sets the EAV/SAV
mode.

Set to 1.
Slow (TC = 2 sec).
Medium (TC = 1 sec).
Fast (TC = 0.2 sec).
Adaptive.
CMG[11:0] = 750d; gain is
1 in NTSC;
CMG[11:0] = 741d; gain is
1 in PAL.
LAGC[1:0] settings decide
in which mode LMG[11:0]
operates.

Notes
CAGC[1:0] settings
decide in which mode
CMG[11:0] operates.
Has an effect only if
CAGC[1:0] is set to
auto gain (10).
Min value is 0d
(G = –60 dB)
Max value is 3750
(G = 5).
Has an effect only if
LAGC[1:0] is set to
auto gain (001, 010,
011,or 100).
Min value:
NTSC 1024 (G = 0.85),
PAL (G = 0.81).
Max value:
NTSC 2468 (G = 2),
PAL = 2532 (G = 2).
HSE = Hsync end.
HSB = Hsync begin.
