The Calibration register is used to set various options for the Black Level Offset Calibration.
Avg[2:0] set the number of OB pixels to average:
000 = 4 pixels,
100 = 64 pixels,
001 = 8 pixels,
101 = 128 pixels,
010 = 16 pixels,
110 = 256 pixels,
011 = 32 pixels,
111 = 512 pixels.
Mode=0, selects Line mode calibration (use OB pixels at start or end of each line).
Mode=1, do not use.
LFrame=0, selects Line mode calibration.
LFrame=1, do not use.
DNS[1:0] selects the Digital Noise Suppression filter setting:
00 = off,
10 = medium,
01 = narrow,
11 = wide.
FastCal=1, enables an option to speedup convergence of the calibration feedback loop.
Hold=1, stops all updates to the Coarse and Fine offset DAC accumulators.
ManCal=1, enables manual calibration. The offset DACs are set to the values in the CDAC and FDAC
registers.
See the Black Level Offset Calibration section for more information.

WaitB Register (Reg. 4, Address 000100)
The WaitA and WaitB registers are concatenated to make up the Wait register.
See OB Pixel calibration section for more information.
OB Lines Register (Reg. 5, Address 000101)
The OB Lines register is used by the Offset Calibration Logic to set the number of Optical Black lines used
for Calibration in the Frame Mode. Do not use.
