Description

PPERS

7:4

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 OCCURENCES OUT OF RANGE

Every proximity cycle generates an interrupt

Generate interrupt after every occurrence.

Generate interrupt after 2 occurrences.

...

Generate interrupt after PPERS occurrences.

Generate interrupt after 15 occurrences.

APERS

3:0

ALS Interrupt Persistence. Defines a filter for the number of consecutive occurrences

that CDATA must remain outside the threshold range between AILT and AIHT before an

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

to 0.

VALUE

CONSECUTIVE OCCURENCES OUT OF RANGE

Every ALS cycle generates an interrupt

Generate interrupt after every occurrence.

Generate interrupt after 2 occurrences.

Generate interrupt after 3 occurrences.

Generate interrupt after 5 occurrences.

Generate interrupt after 10 occurrences.

…

Generate interrupt after 5 X (APERS -3) occurrences.

Generate interrupt after 55 occurrences.

Generate interrupt after 60 occurrences.
