TCS3490 − Register Description
Figure 30:
RGBC Data Registers
RGBC Data Registers (0x94 - 0x9B)
Clear, red, green, and blue data is stored as 16-bit values. The
read sequence must read byte pairs (low followed by high)
starting on an even address boundary (0x94, 0x96, 0x98, or
0x9A) inside the RGBC Data Register block. 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.
