int_th_low
int_th_hi
R/W bit. Indicates a generated interrupt for proximity
R/W bit. Indicates a generated interrupt for als
R/W bit. Indicates a low threshold exceed
R/W bit. Indicates a high threshold exceed
Note
? Once an interrupt is generated the corresponding status bit goes to 1 and stays there unless it is cleared by writing a 1 in the corresponding
bit. The int pad will be pulled down while at least one of the status bit is 1.
