When = 0, no Prox interrupt event has occurred since power-on or last “clear”
When = 1, a Prox interrupt event occurred. Clearable by writing “0”
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
Unused register bit - write 0
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”
For bits 2:1 = (see the following)
00; set ALS_FLAG if 1 conversion is outside the set window
01; set ALS_FLAG if 4 conversions are outside the set window
10; set ALS_FLAG if 8 conversions are outside the set window
11; set ALS_FLAG if 16 conversions are outside the set window
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)
