TMD3721 − Register Overview

The BINSRCH_TARGET field is used by the calibration feature to

set the baseline value for PDATA when no target is present. For

example, calibration of a device in open air, with no target, and

BINSRCH_TARGET setting of 2 causes the PDATA value will be

approximately 15 counts. This feature is useful because it forces

PDATA result to always be above zero.

The PROX_DATA_AVG field sets the number of ADC samples that

are averaged. Each ADC sample causes the programmed

number of proximity pulses to be transmitted. Once all samples

have been completed and the average is calculated, the

proximity state machine will then pass this value either directly

to PDATA.
