3.6.3.1 Operation Select

The Operation Select drop-down menu allows the device operating mode to be switched between the PWRDN, continuous, oneshot (AGC), and oneshot modes. PWRDN is the power-down or standby mode where the device enters a low power state. There is no active light sensing or conversion in the mode. Continuous mode measures and updates the output registers continuously determined by the conversion time. Oneshot keeps the device in standby mode and a conversion is triggered by an interrupt (INT Pin) or a timer measurement. This mode uses auto-range selection logic from the previous selection to decide the range for the current trigger. Oneshot (AGC) keeps the device is standby mode and a conversion is triggered by an interrupt (INT Pin) or a timer measurement. In this mode, every oneshot trigger forces a full reset on the auto-ranging control logic and a fresh auto-range detection is initiated ignoring the previous measurements.
