... Both devices are also ideal for controlling keyboard illumination based upon ambient lighting conditions. Illuminance information can further be used to manage exposure control in digital cameras. The TSL2560/61 devices are ideal in notebook/tablet PCs, LCD monitors, flat-panel televisions, cell phones, and digital cameras. In addition, other applications include street light control, security lighting, sunlight harvesting, machine vision, and automotive instrumentation clusters ...

... ADDR SEL Detailed Description The TSL2560 and TSL2561 are second-generation ambient light sensor devices. Each contains two integrating analog-to-digital converters (ADC) that integrate currents from two photodiodes. Integration of both channels occurs simultaneously. Upon completion of the conversion cycle, the conversion result is transferred to the Channel 0 and Channel 1 data registers, respectively ...

... SMBus read/write protocol requires a Byte Count. All four ADC Channel Data Registers (Ch through Fh) can be read simultaneously in a single SMBus transaction. This is the only 32-bit data block supported by the TSL2560 SMBus protocol. The BLOCK bit must be set to 1, and a read condition should be initiated with a COMMAND CODE of 9Bh. By using a COMMAND CODE of 9Bh during an SMBus Block Read Protocol, the TSL2560 device will automatically insert the appropriate Byte Count (Byte Count = 4) as illustrated in Figure 17 ...
