AGC chroma
AGC luma
Bit 3: 1 must be written to this bit.
Bit 2: 1 must be written to this bit.
AGC chroma: Controls automatic gain in the chroma/B/R/PbPr channel:
0 = Manual (if AGC luma is set to manual, AGC chroma is forced to be in manual)
1 = Enabled auto gain, applies 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: 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 a AGC when this bit is
set to 0.
1 = Enabled auto gain applies only to the embedded sync channel (default)
These settings only affect the analog front-end (AFE). The brightness and contrast of component, CVBS
are not affected by these settings.

000 = Autoswitch mode (default)
Autoswitch mode (default)

NOTE: PAL60 is not included in autoswitch mode.
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.

Power save
Power save:
0 = Normal operation (default)
1 = Power-save mode. Reduces the clock speed of the internal processor and switches off the ADCs. I2C
interface is active and all current operating settings are preserved.
