MODE_CONTROL register (0x41)

CONTROL of PS and ALS operating modes and time settings.

Repetition time is the time between two separate measurements. Integration time is the duration for one

measurement. ALS high sensitivity modes are 1010 and 1011 with an increased integration time of

400ms. In PS operating mode: „normal mode“ only one PS measurement is performed during one PS

repetition time. In PS operating mode „twice mode“ two independent PS measurement are performed

within one PS repetition time. Both measurements are independent and can trigger the interrupt. This

feature can be used to decrease the interrupt update time if the persistence function (register 0x43) is

used.
