TMD2725 − Register Description

Status Register (Address 0x93)

Figure 38:

Status Register

All flags in this register can be cleared by setting the bit high.

Alternatively, if the CFG3.int_read_clear bit is set, then simply

reading this register automatically clears all eight flags.

Bit Description

ASAT

R, SC

The Analog Saturation flag signals that the ALS results

may be unreliable due to saturation of the AFE.

PSAT

R, SC

The Proximity Saturation flag indicates that an ambient-

or reflective-saturation event occurred during a

previous proximity cycle.

5PINT

R, SC

The Proximity Interrupt flag indicates that proximity

results have exceeded thresholds and persistence

settings.

4AINT

R, SC

The ALS Interrupt flag indicates that ALS results

(photopic channel) have exceeded thresholds and

persistence settings.

3CINT

R, SC

The Calibration Interrupt flag indicates that calibration

has completed.

PSAT_REFLECTIVE

R, SC

The Reflective Proximity Saturation Interrupt flag

signals that the AFE has saturated during the IR LED

active portion of proximity integration.

PSAT_AMBIENT

R, SC

The Ambient Proximity Saturation Interrupt flag signals

that the AFE has saturated during the IR LED inactive

portion of proximity integration.
