Register #10 and #11 Low Threshold
Register address = 8Ah and 8Bh. These registers contain the low threshold value. The value is a 16 bit word. The high byte is
stored in register #10 and the low byte in register #11.
Register #12 and #13 High Threshold
Register address = 8Ch and 8Dh. These registers contain the high threshold value. The value is a 16 bit word. The high byte is
stored in register #12 and the low byte in register #13.
Register #14 Interrupt Status Register
Register address = 8Eh. This register contains information about the interrupt status for either proximity or ALS function and
indicates if high or low going threshold exceeded.
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.
