Detail Description
A hardware reset (by asserting XRST) should be
performed before starting any operation.
The user controls and configures the device by
programming a set of internal registers through a
serial interface. At the start of application, the
following setup data must be written to the setup
registers:
Sensor Gain Settings
The sensor gain can be adjusted by varying the
photodiode size and integration time of the sensor
manually through the following registers.
Sensor Sensitivity ~ Photodiode Size x Integration
Time Slot
Setup Value for Photodiode Size
The following value can be written to each of the
photodiode size registers to adjust the gain of the
sensor. The default value after reset for these
registers is 07H.

Setup Value for Integration Time
The following value can be written to each of the
integration time registers to adjust the gain of the
sensor. The default value after reset for these
registers is 07H.
Sensor ADC Output Registers
To obtain sensor ADC value, ‘02’ Hex must be written
to ACQ register before reading the Sensor ADC Output
Registers.
