FSCLE Fsc Lock Enable, Address 0x51 [7]
The FSCLE bit allows the user to choose whether 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_1.
This bit must be set to 0 when operating in YPrPb component
mode to generate a reliable HLOCK status bit.
Rev. 0 | Page 25 of 112
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 Fsc lock.
VS_Coast[1:0], Address 0xF9 [3:2]
These bits are used to set VS free-run (coast) frequency.

CIL[2:0] Count Into Lock, Address 0x51 [2:0]
CIL[2:0] determines the number of consecutive lines for which
the into-lock condition must be true before the system switches
into the locked state, and reports this via STATUS_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 for which
the out-of-lock condition must be true before the system switches
into unlocked state, and reports this via STATUS_0[1:0]. It
counts the value in lines of video.

ST_NOISE[10:0] HS Tip Noise Measurement, Address 0xDE
[2:0], 0xDF [7:0]
The ST_NOISE[10:0] measures, over four fields, a readback
value of the average of the noise in the HSYNC tip.
ST_NOISE_VLD must be 1 for this measurement to be valid.
1 bit of ST_NOISE[10:0] = 1 ADC code.
1 bit of ST_NOISE[10:0] = 1.6 V/4096 = 390.625 μV.
COLOR CONTROLS
These registers allow the user to control the picture appearance,
including control of the active data in the event of video being
lost. These controls are independent of any other controls. For
instance, brightness control is independent of picture clamping,
although both controls affect the signal’s dc level.
CON[7:0] Contrast Adjust, Address 0x08 [7:0]
This register allows the user to adjust the contrast of the picture.
Table 28. CON Function
CON[7:0]
Description
0x80 (default)
Gain on luma channel = 1
0x00
Gain on luma channel = 0
0xFF
Gain on luma channel = 2
SD_SAT_Cb[7:0] SD Saturation Cb Channel, Address 0xE3 [7:0]
This register allows the user to control the gain of the Cb channel
only. The user can adjust the saturation of the picture.
Table 29. SD_SAT_Cb Function
SD_SAT_Cb[7:0]
Description
0x80 (default)
Gain on Cb channel = 1
0x00
Gain on Cb channel = 0
0xFF
Gain on Cb channel = 2
