Register Description
Following are detailed descriptions of the control registers related to the operation of the ISL29125 ambient light sensor device. These
registers are accessed by the I²C serial interface. For details on the I²C interface, refer to “Serial Interface” on page 6.
All the features of the device are controlled by the registers. The ADC data can also be read. The following sections explain the details of
