Invert polarity of LED_OUT output. When set, the
output pin LED_OUT is pulsed low when the sensor is
undergoing exposure.
0 = Invalid.
1 = Invalid.
2 = 10-bit linear.
3 = 12-to10-bit companding.

Range: 1.0–2.1V; Default: 1.4V
V
V_Step = bits (4:0) x 62.5mV + 0.5625V.
Range: 0.5625 - 2.5V; Default: 2.375V.
Usage: V_Step1 HiDy voltage.
V_Step = bits (4:0) x 62.5mV + 0.5625V.
Range: 0.5625 - 2.5V; Default: 2.0625V.
Usage: V_Step2 HiDy voltage.
V_Step = bits (4:0) x 62.5mV + 0.5625V.
Range: 0.5625 - 2.5V; Default: 1.875V.
Usage: V_Step3 HiDy voltage.
V_Step = bits (4:0) x 62.5mV + 0.5625V.
Range: 0.5625 - 2.5V; Default: 0.8125V.
Usage: V_Step HiDy parking voltage, also provides anti-
blooming when V_Step is disabled.
Analog gain = bits (6:0) x 0.0625 for values 16–31:
Analog gain = bits (6:0)/2 x 0.125 for values 32–64
For values 16–31: each LSB increases analog gain
0.0625v/v. A value of 16 = 1X gain. Range: 1X to
1.9375X.
For values 32–64: each 2 LSB increases analog gain
0.125v/v. Range: 2X to 4X. An LSB increase of 1 will not
increase the gain; the value must be incremented by 2.
No exception detection is installed and caution should
be taken when programming.
