TMD2621 − Register Overview

CALIBCFG Register (Address 0xD9)

Figure 51:

CALIBCFG Register

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

Addr: 0xD9

PROX_AUTO_

OFFSET_

ADJUST

0RW

If set, then in proximity mode, whenever an ADC

measurement yield zero, the pertinent offset register will

be decreased. Will set the OFFSET_ADJUSTED flag if it

happened. Note that if a diode is disabled, this

mechanism is disabled as well.
