Register #7 and #8 Proximity Measurement Result Register
Register address = 87h and 88h. These registers are the result registers for proximity measurement readings.
The result is a 16 bit value. The high byte is stored in register #7 and the low byte in register #8.
Register #9 Interrupt Control Register
Register address = 89h.

Description
Int count exceed
R/W bits. These bits contain the number of consecutive measurements needed above/below the
threshold
000 - 1 count = DEFAULT
001 - 2 count
010 - 4 count
011 - 8 count
100 -16 count
101 - 32 count
110 - 64 count
111 - 128 count
INT_PROX_ready_EN R/W bit. Enables interrupt generation at proximity data ready
INT_THRES_EN R/W bit. Enables interrupt generation when high or low threshold is exceeded
INT_THRES_SEL R/W bit. 0: thresholds are applied to proximity measurements
