All rights reserved. ex3 ) Ambient light sensor interrupt function In case of unlatch mode if the measurement value is within the range set by ALS interrupt threshold ‘H’ and “L” value, the interrupt becomes inactive. And if the measurement value is out of the range set by threshold ‘H’ and ”L” value, the interrupt becomes active. In case of latch mode once the interrupt becomes active, it keeps the status until end of measurement after INTERRUPT register is read. In case that persistence function is set to active, if the interrupt is inactive, it keeps inactive status until the measurement value is continuously out of the range set by threshold ‘H’ and “L” value. If the interrupt is active, it keeps active status until the measurement value is continuously within the range set by threshold ‘H’ and ”L” value or until end of measurement after INTERRUPT register is read. Master reads INTERRUPT register Unlatch mode ALS interrupt threshold ‘H’ level ALS interrupt threshold ‘L’ level Sequential measurement result time Latch mode Unlatch mode persistence = 2 active inactive Sequential measurement result |
