TCS3472 − Register Description

RGBC Channel Data Registers (0x14 – 0x1B)

Clear, red, green, and blue data is stored as 16-bit values. To

ensure the data is read correctly, a two-byte read I²C transaction

should be used with a read word protocol bit set in the

command register. With this operation, when the lower byte

The upper register will read the correct value even if additional

ADC integration cycles end between the reading of the lower

and upper registers.
