FUNCTION NAME
ABLC enabled: digital offset control. A 1LSB change in
this register will shift the ADC output by 1 LSB.
ABLC disabled: analog offset control. These bits go to
the upper 8-bits of the 10-bit offset DAC. A 1LSB
change in this register will shift the ADC output
approximately 1 LSB (Offset DAC range = 0) or
0.5LSBs (Offset DAC range = 1).
0x00 = min DAC value or -0x80 digital offset,
0x80 = mid DAC value or 0x00 digital offset,
0xFF = max DAC value or +0x7F digital offset
0: ±½ ADC fullscale (1 DAC LSB ~ 1 ADC LSB)
1: ±¼ ADC fullscale (1 DAC LSB ~ ½ ADC LSB)
Set to 0.
These bits are the LSBs necessary for 10-bit manual
offset DAC control.
Combine with their respective MSBs in registers 0x09,
0x0A, and 0x0B to achieve 10-bit offset DAC control.
Value doesn’t matter
3dB point for AFE lowpass filter
000b: 100MHz
111b: 780MHz (default)
0x0: Peaking off
0x1: Moderate peaking
0x2: Maximum recommended peaking (default)
Values above 2 are not recommended.
14-bit HTOTAL (number of active pixels) value
The minimum HTOTAL value supported is 0x200.
HTOTAL to PLL is updated on LSB write only.
relative to the period of a pixel. Adjust to obtain
optimum image quality. One step = 5.625° (1.56% of
pixel period).
Number of lines the PLL will coast prior to the start of
VSYNC.
Number of lines the PLL will coast after the end of
VSYNC.
