Register Set
The device 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 Table 1.

ica _{The mechanics of accessing a specific register depends on the specific protocol used. See the section on I}²_C
protocols on the previous pages. In general, the COMMAND register is written first to specify the specific
Techn ^{control/status register for following read/write operations.}
