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
register is read, the upper eight bits are stored into a shadow
register, which is read by a subsequent read to the upper 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.
