Command Code #6: Interrupt Status
Command code address = 06h. Bit 15 defines interrupt flag while trigger occurred due to data crossing low threshold windows.
Bit 14 defines interrupt flag while trigger occurred due to data crossing high threshold windows.
REFRESH TIME DETERMINATION OF PSM
VEML7700’s refresh time can be determined by PSM and ALS_IT setting in power saving mode (PSM). Cooperating with the
command register setting, the designer has a flexible method in defining the timing, power consumption, and sensitivity for light
data collection.
