54 / 87

Default value

Description of the value

Exp_kp2

51[7:0]

52[7:0]

53[7:0]

Defines the exposure time of kneepoint 2. Formula:

129 ∗ ��_��(0.43 ∗ ��_��ℎ + ��_��2)

Where clk_per is the period of the CLK_IN input

clock.

Vlow3

90[6:0]

Defines the Vlow3 voltage (DAC setting).

Bit [6] = Enable

Bit[5:0] = Vlow3 value

Vlow2

89[6:0]

Defines the Vlow2 voltage (DAC setting).

Bit [6] = Enable

Bit[5:0] = Vlow2 value

Piecewise linear response with EXTERNAL exposure mode:

When external exposure time is used and a piecewise linear response is desired, the following

registers should be programmed. Note that the combination of the piecewise linear response

and interleaved read-out is not possible.

Default value

Description of the value

Nr_slopes

54[1:0]

Defines the number of slopes (min=1, max=3).

Vlow3

90[6:0]

Defines the Vlow3 voltage (DAC setting).

Vlow2

89[6:0]

Defines the Vlow2 voltage (DAC setting).

The timing that needs to be applied in this external exposure mode looks like the one shown in

Figure 49.

FRAME_REQ

T_EXP1

Total exposure time

Exposure kp2

Exposure kp1
