FSCLE, F
The FSCLE bit allows the user to choose if the status of the
color subcarrier loop is taken into account when the overall
lock status is determined and presented via Bits [1:0] in Status
Register 1. The FSCLE bit must be set to 0 when operating in
YPrPb (component) mode to generate a reliable horizontal lock
status bit (INST_HLOCK).
0 (default)—Makes the overall lock status dependent on the
horizontal sync lock.
1—Makes the overall lock status dependent on the horizontal
sync lock and the F
CIL [2:0], Count-Into-Lock, Address 0x51 [2:0]
CIL [2:0] determines the number of consecutive lines the system
must remain in the into-lock condition before reporting a locked
state in Status Register 1 [1:0]. It counts the value in lines of video.

COL [2:0], Count-Out-of-Lock, Address 0x51 [5:3]
COL [2:0] determines the number of consecutive lines the system
must be in the out-of-lock condition before reporting an unlocked
state in Status Register 0 [1:0]. It counts the value in lines of video.

ST_NOISE_VLD, Sync Tip Noise Measurement Valid,
Address 0xDE [3], Read Only
This read-only bit measures whether ST_NOISE is valid or invalid.
0—The ST_NOISE [10:0] measurement is invalid.
1 (default)—The ST_NOISE [10:0] measurement is valid.
ST_NOISE [10:0], Sync Tip Noise Measurement,
Addresses 0xDE [2:0], 0xDF [7:0]
The ST_NOISE [10:0] measures the noise in the horizontal sync
tip over four fields and shows a readback value of the average noise.
ST_NOISE_VLD must be 1 for this measurement to be valid.
One bit of ST_NOISE [10:0] = one ADC code.
One bit of ST_NOISE [10:0] = 1.6 V/4096 = 390.625 μV.
COLOR CONTROLS
These registers allow the user to control the appearance of the
picture, including control of the active data in the event of video
being lost. These controls are independent of any other control.
For instance, brightness control is independent of picture clamping,
although both controls affect the dc level of the signal.
CON [7:0], Contrast Adjust, Address 0x08 [7:0]
These bits allow the user to adjust the contrast of the picture.

SD_SAT_CB [7:0], SD Saturation Cb Channel,
Address 0xE3 [7:0]
These bits allow the user to control only the gain of the Cb
channel. The user can adjust the saturation of the picture.
