Register Set
The LUMENOLOGY r Company
The TCS3404/14 is controlled and monitored by 18 user 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 Table 2.
The mechanics of accessing a specific register depends on the specific SMB protocol used. Refer to the section
on SMBus protocols on the previous pages. In general, the COMMAND register is written first to specify the
specific control/status register for following read/write operations.
