REGISTER 0x02 (INTERRUPT) - PROX/ALS INTERRUPT CONTROL BIT # ACCESS DEFAULT BIT NAME FUNCTION/OPERATION 7FLAG 0x00 PROX_FLAG (Prox Flag) 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” 6:5 RW 0x00 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 4RW 0x00 Unused (Write 0) Unused register bit - write 0 3 FLAG 0x00 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” 2:1 RW 0x00 ALS_PRST (ALS Persist) 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 0RW 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) TABLE 5.
