TCS3701 − Register Overview

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.

Proximity Interrupt Thresholds

Note(s):

1. Return to the Register Map (0x88, 0x89, 0x8A, 0x8B, 0x8C, 0x8D, 0x8E, 0x8F).

The proximity configuration registers include fields used to

control proximity operation.

Note(s):

1. Using features described in CFG14 may lead to malfunction if not properly applied. Please contact ams OSRAM application support

for help.

2. Return to the Register Map (0xB7).

AUTO_CO_CAL_EN

R/W

Automatic Coarse Calibration Enable. If asserted,

the coarse offset range is calibrated automatically.

EN_PRX_OFFSET_

RANGE

0R/W

Coarse Offset Range Enable. If asserted, the

coarse offset range is enabled.

4:0

PRX_OFFSET_COARSE

R/W

Proximity Offset Range. If AUTO_CO_CAL_EN and

EN_PRX_OFFSET_RANGE are enabled, the offset

range is set automatically and can be read here. If

they are not enabled, the user programs the offset

range here.
