PS_DATA_LSBs register (0x44h)

LSB of the PS output.

PS_DATA_MSBs register (0x45h)

MSB of the PS output.

0000 Interrupt becomes active after each measurement

(The mode indicates that a PS or ALS measurement has been finished and can

be read via the register. It is independent of the ALS & PS measurement value

and threshold settings)

0001 Interrupt status is updated after each measurement

(The interrupt status is updated independently after each measurement. Active

or Inactive status of the interrupt is depending on the values of the last

measurement in combination with the interrupt settings :“interrupt mode“

(register 0x4Ah) and „thresholds“ register 0c4Ch and following.)

0010 Interrupt status is updated if two consecutive threshold

judgement are the same

(The interrupt status only changes if the interrupt judgement of 2 consecutive

measurement results are the same and different to the current interrupt status.)

0011 ... 1111 Interrupt status is updated if threshold judgement are

the same over consecutive set times (3 .. 15)

(This is the same procedure like in the 0010 persistence mode, but instead of

2 consecutive threshold judgments more are needed (3 to 15 depending on the

setting) to change the interrupt status.)

e.g.:

1010: 10 measurement results in a row need to fulfill the interrupt judgement to

update the interrupt status
