TMD2712 − Register Description

CALIB_OFFSET Register (Address 0xD8)

Figure 53:

CALIB_OFFSET Register

For applications with high optical proximity crosstalk (the

emitted IR optical signal appears at the IR sensor), the offset

range can be extended in discrete steps. To determine the best

range extension step for the application, a proximity calibration

cycle is initiated and the resulting proximity offset is captured

in the POFFSETL/H registers.

Setting this bit to a 1 enables the proximity offset range

extension functionality. See the OFFSET_RANGE_

EXTENSION bits. If this bit is set to 0, the offset range

extension is disabled.
