Bit 3: 1 must be written to this bit.
Bit 2: 1 must be written to this bit.
AGC chroma enable: Controls automatic gain in the chroma/PbPr channel:
0 = Manual (if AGC luma is set to manual, AGC chroma is forced to be in manual)
1 = Enabled auto gain, applied a gain value acquired from the sync channel for S-video and component
mode. When AGC luma is set, this state is valid. (default)
AGC luma enable: Controls automatic gain in the embedded sync channel of CVBS, S-video, component
video:
0 = Manual gain, AFE coarse and fine gain frozen to the previous gain value set by AGC when this bit is set
to 0.
1 = Enabled auto gain applied to only the embedded sync channel (default)
These settings only affect the analog front-end (AFE). The brightness and contrast controls are not affected
by these settings.

With the autoswitch code running, the user can force the decoder to operate in a particular video standard
mode by writing the appropriate value into this register. Changing these bits causes the register settings to
be reinitialized.
NOTE: Sampling rate (either square pixel or ITU-R BT.601) can be set by bit 7 (sampling rate)
in the output formatter 1 register at I2C subaddress 33h (see Section 2.11.28).
