PROX_PRST

(Prox Persist)

For bits 6:5 = (see the following)

00; set PROX_FLAG if 1 conversion result trips the threshold value

01; set PROX_FLAG if 4 conversion results trip the threshold value

10; set PROX_FLAG if 8 conversion results trip the threshold value

11; set PROX_FLAG if 16 conversion results trip the threshold value

3FLAG0x00

ALS_FLAG

(ALS FLAG)

When = 0, no ALS interrupt event has occurred since power-on or last “clear”

When = 1, an ALS interrupt event occurred. Clearable by writing “0”

ALS_PRST

(ALS Persist)

For bits 2:1 = (see the following)

00; set ALS_FLAG if 1 conversion is outside the set window

0x00

INT_CTRL

(Interrupt Control)

When = 0, set INT pin low if PROX_FLAG or ALS_FLAG high (logical OR)

When = 1, set INT pin low if PROX_FLAG and ALS_FLAG high (logical AND)
