Register Map
There are ten 8-bit registers accessible via I
store the various ALS/IR/Prox thresholds which trigger interrupt events. Registers 0x8 through 0xA store the results of ALS/IR/Prox ADC
conversions.

TABLE 1. ISL29030A REGISTERS AND REGISTER BITS
PROX_SLP[2:0]
When = 0, proximity sensing is disabled
When = 1, continuous proximity sensing is enabled. Prox data will be ready 0.54ms after this bit is
set high
For bits 6:4 = (see the following)
111; sleep time between prox IR LED pulses is 0.0ms (run continuously)
110; sleep time between prox IR LED pulses is 12.5ms
101; sleep time between prox IR LED pulses is 50ms
100; sleep time between prox IR LED pulses is 75ms
011; sleep time between prox IR LED pulses is 100ms
010; sleep time between prox IR LED pulses is 200ms
001; sleep time between prox IR LED pulses is 400ms
000; sleep time between prox IR LED pulses is 800ms
When = 0, IRDR behaves as a pulsed 110mA current sink
When = 1, IRDR behaves as a pulsed 220mA current sink
When = 0, ALS/IR sensing is disabled
When = 1, continuous ALS/IR sensing is enabled with new data ready every 100ms
When = 0, ALS is in low-lux range
When = 1, ALS is in high-lux range
When = 0, ALS/IR data register contains visible ALS sensing data
When = 1, ALS/IR data register contains IR spectrum sensing data
