TMG3992 − Register Description

RGBC Data Registers (0x94 − 0x9B)

Red, green, blue, and clear 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

The upper register will read the correct value even if additional

ADC integration cycles end between the reading of the lower

and upper registers.

RGBC Data Registers

Note(s):

1. When reading register contents, a read of the lower byte data automatically latches the corresponding higher byte data (16 bit

latch). This feature guarantees that the high byte value has not been updated by the ADC between I²C reads. In addition, reading

CDATAL register not only latches CDATAH but also latches all eight RGBC register simultaneously (64 bit latch).

Proximity Data Registers (PDATA 0x9C)

Proximity data is stored as an 8-bit value.
