TCS3472 − Register Description
Register Description
Figure 24:
Register Set
The TCS3472 is controlled and monitored by data registers and
a command register accessed through the serial interface.
These registers provide for a variety of control functions and
can be read to determine results of the ADC conversions. The
register set is summarized in Figure 24.

The mechanics of accessing a specific register depends on the
specific protocol used. See the section on I²C protocols on the
previous pages. In general, the COMMAND register is written
first to specify the specific control-status-data register for
subsequent read/write operations.
