TCS3771 − Principles of Operation
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.

Proximity Data Registers (0x1C − 0x1D)
Proximity data is stored as a 16-bit value. 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.
