0x20
PLL Phase, (0x00)
5:0
PLL Sampling Phase
Used to control the phase of the ADC’s sample point relative
to the period of a pixel. Adjust to obtain optimum image quality.
One step = 5.625° (1.56% of pixel period).

Pre-coast
Number of lines the PLL will coast prior to the start of VSYNC.
0x22
PLL Post-coast, (0x04)
7:0
Post-coast
Number of lines the PLL will coast after the end of VSYNC.
0x23

DC Restore and ABLC
starting pixel MSB, (0x00)
5:0
DC Restore and ABLC
starting pixel (MSB)
Pixel after Raw HSYNC trailing edge to begin DC restore and
ABLC. 14-bits.

DC Restore Clamp Width,
(0x10)
7:0
DC Restore clamp width
Only applies to DC restore clamp used for AC-coupled
configurations. A value of 0x00 means the clamp DAC is never
connected to the input.
