2.4 Operating modes
Table 5. describes the operating modes of this device.
• Modes 1 and 2 are single-shot range and ALS measurements.
• Modes 3 and 4 are stand-alone, continuous operation for either range or ALS.
• Modes 5 and 6 are for mixed continuous and single-shot mode operations where
regular measurements are required from one of the sensors and only occasional
measurements are required from the other.
Note: In modes 5 and 6, single-shot operation takes the priority i.e. if a scheduled measurement is
in progress when the host requests a single-shot measurement, the scheduled
measurement will be aborted and will resume on the next available time slot.
• Mode 7 allows both ALS and range measurements to be scheduled at regular intervals.
The ALS measurement is completed first immediately followed by a range
measurement. Interleaved mode is described in more detail in Section 2.4.3.
