The DECA has a low-power, reflectance-based, infrared proximity and ambient light sensor (Si1143)
with I2C digital interface and programmable-event interrupt output. The Si1143 is an active optical
reflectance proximity detector and ambient light sensor whose operational state is controlled
through registers accessible through the I2C interface. The host can command the Si1143 to initiate
on-demand proximity detection or ambient light sensing.
