TMD2725 − Register Description

The SAI bit sets the device operational mode following the

completion of an ALS or proximity cycle. If AINT and AIEN are

both set or if PINT and PIEN are both set, causing an interrupt

on the INT pin, and the SAI bit is set, then the oscillator will

deactivate. The Device will appear as if PON = 0, however, PON

will read as 1. The device can only be reactivated (oscillator

enabled) by clearing the interrupts in the STATUS register.

POFFSETL Register (Address 0xC0)

Figure 46:

POFFSETL Register

Typically, optical and/or electrical crosstalk negatively

influence proximity operation and results. The

POFFSETL/POFFSETH registers provide a mechanism to remove

system crosstalk from the proximity data. POFFSETL and

POFFSETH contains the magnitude and sign of a value which

adjusts PDATA generated in the AFE. An offset value in the range

of ± 255 is possible.
