Basic Operation
After applying VDD, the device will initially be in the power-down state. To operate the device, issue a command
to access the CONTROL register followed by the data value 01h to the CONTROL register to power up the
device. The TIMING register should be configured for the preferred integration period, and then the ADC_EN
should be set to 1 to enable both ADC channels.
For example code that illustrates initializing and reading the device, see TAOS Designer’s Notebook Number
