Register
Read Mode 1
In read mode 1, this register is used to control many aspects of the readout of the sensor.
Gain Settings
The gain is individually controllable for each of the four groups of pixels that lie in odd rows and columns, even rows and
columns, odd rows and even columns, and even rows and odd columns. This is shown in the register chart.
Formula for gain setting:
Gain ≤ 8
Gain > 8 (bit[6] = 1 and bit[5] = 1)
Since bit[6] of the gain registers are multiplicative factors for the gain settings, there are alternative ways of achieving
certain gains. Some settings offer superior noise performance to others, despite the same overall gain. The following lists
the recommended gain settings:
1.000 to 4.000
4.25 to 8.00
9.0 to 15.0
0x2B
0x2C
0x1E
Gain
Gain = (bit[6] + 1) x (bit[5-0] x 0.125)
Gain = 8.0 + bit[2-0]

Snapshot Mode
1 = enable (wait for TRIGGER; TRIGGER can come from outside signal (TRIGGER pin on the sensor)
or from serial interface register restart, i.e. programming a “1” to bit 0 of Reg0x0B.
STROBE Enable
1 = enable STROBE (signal output from the sensor during the time all rows are integrating. See
STROBE width for more information).
STROBE Width

1 = extend STROBE width (STROBE signal width extends to entire time all rows are integrating).
Strobe Override
1 = override STROBE signal (STROBE signal is set HIGH when this bit is set, LOW when this bit is set
LOW. It is assumed that STROBE enable is set to “0” if STROBE override is being used).
