NAME
DESCRIPTION
D8, D9
OMUX1,
OMUX0
These two bits multiplex digital output (data presented at D[9:0] pins):
OMUX1
OMUX0
0
D[9:0] = ADC output (default)
0
1
D[9:0] = ADC output
1
0
D[9] = fine/coarse (1/0) autocorrection flag
D[8] = coarse DAC sign
D[7:0] = coarse DAC value
1
D[9] = fine/coarse (1/0) autocorrection flag
D[8] = fine DAC sign
D[7:0] = fine DAC value
D7
HYS
Sets the hysteresis
0 = Apply hysteresis to FDAC (default)
1 = No hysteresis
D6
X
Reserved
D5, D4
SOFW1,
SOFW0
These two bits set the digital filter weight when SOF is activated (the SOF bit in control register 2 is set to 1).

MP
When this bit is 1, the number of optical black pixels to be averaged per line (2N) is multiplied by 3.
By setting the MP and PN2PN0 bits together, the number of optical black pixels can be programmed to have the follow-
ing numbers:
1, 2, 3 (1X3), 4, 6 (2
×3), 8, 12 (4×3), 16, 24 (8×3), 32, 48 (16×3), 64, 96 (32×3), and 192 (64×3).
Default: MP = 0, no multiplication
D2D0
PN2PN0
Number of optical black pixels per line to average = 2N
N can be 0, 1, 2, 3, 4, 5, and 6. Or number of pixels per line can be 1, 2, 4, 8 (default), 16, 32, or 64.
The maximum number of pixels per line is 64, even if N>6.
Default optical black calibration register value = 0000000011
