TCS3707 − Register Overview

Proximity Configuration

Proximity can be executed with its own sample rate

independent of and parallel to ALS/color integration. However,

ambient flicker detection will not be valid if proximity occurs

during flicker data collection. If ambient flicker detection is

enabled, it is recommended to assert the PROX_BEFORE_EACH_

ALS field. In this case, PTIME is ignored and the proximity state

is executed before each ALS/color cycle. If PTIME is too short

for the number of pulses and pulse length configured for

proximity, PROX_TRIGGER_ERROR will be 1.

Note(s):

1. Return to the Register Map (0x82).

The Proximity Interrupt Threshold Registers set the high and

low trigger points for the comparison function which generates

an interrupt. Interrupt generation is subject to the value set in

persistence filter (PPERS). These registers are read/write.
