Notes:
IRQ_ENABLE[5]
IRQ_ENABLE[1:0]
1. For ALS_IR channel, interrupts per sample is not possible without also enabling ALS_VIS
2. All other combinations are invalid and may result in unintended operation
3. There is hysteresis applied (ALS_TH) and history checking (ALS_HISTORY). ALS_LOW_TH, ALS_HI_TH,

No ALS Interrupts
ALS_INT [0] set after every ALS_VIS sample
Monitors ALS_VIS, ALS_INT [0] upon exiting region
between low and high thresholds (ALS_LOW_TH and
ALS_HI_TH)

between low and high thresholds (ALS_LOW_TH and
ALS_HI_TH)
Monitors ALS_IR, ALS_INT [1] set upon entering region
between low and high thresholds (ALS_LOW_TH and
ALS_HI_TH)
No CMD Interrupts
CMD_INT set when there is a new RESPONSE
CMD_INT set when there is a new error code in
