Bit Description

7:4

PPERS

R/W

Proximity Interrupt Persistence. Defines a filter for the number of

consecutive occurrences that PDATA must remain outside the

threshold range between PILT and PIHT before an interrupt is

generated. Any sample that is inside the threshold range resets the

counter to 0.

VALUE

CONSECUTIVE PDATA OUT OF RANGE TO INTERRUPT

Every proximity cycle generates an interrupt.

…PPERS

3:0

APERS

R/W

ALS Interrupt Persistence. Defines a filter for the number of

consecutive occurrences that ALS/color data must remain outside

the threshold range between AILT and AIHT before an interrupt is

generated. The ALS data channel used for the persistence filter is set

by ALS_TH_CHANNEL. Any sample that is inside the threshold range

resets the counter to 0.

VALUE

CONSECUTIVE ADATA OUT OF RANGE TO INTERRUPT

Every ALS cycle generates an interrupt.
