TMD3702VC − Register Description

The binary search 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 BINSEARCH_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_AVG field sets the number of ADC samples that are

averaged to calculate the PDATA result.

OFFSET_

ADJUSTED

0RW

Bit is set when the proximity offset has been

automatically decremented if AUTO_OFFSET_

ADJ = 1 (see CALIBCFG register). This bit can

be cleared by writing 1 to it or setting AUTO_

OFFSET_ADJ to 0.

CALIB_FINISHED

This flag indicates that calibration has

finished. This bit is a copy of the CINT bit in the

STATUS register. It will be cleared when the

CINT bit is cleared.
